7-5-13 North and South Kinsman, Fishin Jimmy Trail, Lonesome Lake, Kinsman Quartz Monzonite

After celebrating the Fourth of July with a night of fire works in Gorham I was seriously thinking of hiking up into King Ravine early Friday morning. It had rained heavily the evening before and Mts. Madison and Adams (seen here from the Durand Rd. in Randolph) were enshrouded with mist including a smooth lenticular cloud poised above Mt. Adams.  On the west side of the range heavy mist was descending into the valley.  One plan I had was to hike through Kings Ravine and come down via Castellated Ridge but I opted for something different.

I had a yen for a hike worthy of a perfect summer day and, instead I headed west choosing North and South Kinsman, by way of the Lonesome Lake Trail and the Fishin' Jimmy Trail. This ancient yellow birch in the photo stands guard at the bottom of the Lonesome Lake Trail. It's a little over 3 feet in diameter, a giant in this region, and hundreds of years old.

A yellow birch that had the misfortune to start its life on top of a rock.

I had the trail to myself....

...until the height of land and got in proximity to the lake and the Appalachian Mountain Club (AMC) Lonesome Lake Hut  where I began meeting other hikers who had spent the night at the hut and were out early. Hot weather over the past week had been generating afternoon thunderstorms across the region. This young woman was heading to Greenleaf Hut via the Franconia Ridge and got an early start to avoid being caught in a thunderstorm on the ridge. (In the White Mountains the word "thumper" is often used to mean "thunderstorm". Derivation unknown but probably crew members of the AMC huts.)

That was also the case for these two. They were nervous about being caught on Franconia Ridge in a "thumper" after hearing wild stories of what it's like on the unprotected, knife-like ridge crest in severe storms. They asked for my advice, but they're own plan: to get out early, keep a steady and moderate pace, try to get up to the ridge around noon, and be off the summit of Lafayette around 3:30, or 4:00 pm at the latest, was brilliant. When I used to guide this trip--from Lonesome to Greenleaf via the ridge on a hot July day--I would try to do exactly what these two hikers were planning, but not without some near misses. Most of those had their humorous sides like the trip member who dragged along because of the hot, humid weather, making us later and later, protesting that they were going as fast as they possibly could, until we were on the ridge and suddenly there was this ripping, tearing crashing, booming, terrifying peal of thunder right over our heads and I have never, ever seen such a tired, woeful person suddenly have the vitality of a quarter horse and beat us all to the hut by a mile. Fear is sometimes a wonderful motivator.

This group had the same apprehensions about thunderstorms and were considering the odds (on Friday) of encountering a thunderstorm as they hiked the exposed, two-mile length of the ridge. Thunderstorms in the mountains are scary, particularly if there's absolutely no protection. When and where storms are likely hikers have to move efficiently, safely, staying together, and using common sense. Franconia Ridge has two exit trails at either end: Falling Waters Trail which descends from the summit of Little Haystack Mt, at the southern end of the ridge, and the Greenleaf Trail at the north end which descends from  the summit of Lafayette down to Greenleaf Hut. The advantage the hiker has on Franconia Ridge is visibility. You can see and hear storms coming from a long way off and have enough time to make key decisions, but if you are caught out on the ridge when one hits and, if its safe, you can descend into the trees but only on the east side of the ridge and down just a few feet,  until you're below the height of the ridge, and sit down, preferably on something dry (or at least something that's a poor electrical conductor like a backpack, etc), and wait the storm out. Leaving the trail and descending more than a few feet has its own risks. Also, statistics over the years have underlined that it's NOT safe to seek shelter in caves.

They were not particularly concerned about lightning.

Kinsman Quartz Monzonite aka Kinsman Granodiorite. From Lonesome Lake Hut west, including the Kinsmans, you are walking on what's now called Kinsman Quartz Monzonite and what used to be referred to as Kinsman Granodiorite (KGD). The name changed sometime between 1935 and 1970.

One comparison to make with the Conway granite is that the KZM is rougher in texture and offers better traction for climbing than the Conway granite which has a finer, smoother texture. In the photo you can see the larger grains on quartz and the rough texture.

A map from Charles William's 1935 study of the geology in the Franconia qaudrangle. The blue circle, (Ed: I drew both of the colored circles on this man) represents the Conway granite (CG) that Cannon Mt. and several other mountains in the region were formed over long periods of time. The area outside the blue circle is dominated by the Kinsman grandodiorite as identified by Williams and now called Kinsman Quartz Monzonite (KQZ). The green circle represents the position of Lonesome Lake relative to the area of Conway granite based on William's mapping in 1935. In 1970 Brian Fowler suggested from his own field work (Appalachia June 1970, pg. 108) around Lonesome Lake, particularly his "stone counts", that the southern edge of the Conway granite was right meaning right under the hut and about a 1/4 mile closer to the joint between the Conway granite and the Kinsman quartz monozite that was originally suggested by Williams.

A miraculous set of stairs!

Williams, in his June 1934 Appalachia article (p. 69) does a good job of outlining the geologic history of the Franconia quadrangle and particularly the the history of these two rock types. He goes back to the early Paleozoic, which by its name alone we know is a long, long time ago, and a period of mountain building called the Appalachian Uplift (roughly 480 million years ago). We know now that the uplifting, or folding of the crust, was caused by continents crunching into each other at their edges. (Continental Drift, or Tectonic Plate Movement). Williams observed that "at the time of the folding which contorted the bedded (sedimentary) rocks large bodies of magma invaded the crust from below, although did not reach the surface existing at that time." The bodies of magma were 10-12 miles long and 3-6 miles wide. It consolidated there under the crust, a few miles down, forming a granodiorite which has been called the Kinsman granodiorite. (or its modern name Kinsman quartz monozite the name we'll stick with). That's KZM in the photo on these steep slabs. There are large exposures of it on the North and South Kinsman summits. 

The first time up or down these stairs requires a few moments to actually trust them because they appear to be sitting there and not attached to anything, or maybe by some bubble gum,  but they're completely safe and trustworthy.

Following the arrival of the Kinsman granitediorite and as more molten rock came into the area but not quite to the surface the Bickford granite, Scrag granite and the Franconia breccia, are all deposited in the area and are incorporated into the Kinsman granitediorite. These minor periods of volcanic activity finally bring us to ones discussed earlier in this blog in the Moat Mountain article a few years ago, which elaborates on the dramatic periods of volcanic activity which involved major flows of lava now found in the Ossipees, the Belknaps. on Mt. Kearsarge, Moat Mt., Owl's Head, Mt. Hale, and North Twin. Williams further describes the large magma reservoir below the crust in this area that, when it cooled, resulted in the numerous ring dikes in what is now central New Hampshire and found in the Ossipee and Belknap Mountains, the Percy Peaks, as well as in the Franconia region. The ring dikes in the Franonias, compared to the other areas, are poorly preserved due to more cutting by magma surging upwards below the crust. This last bit brings us to the arrival of the Lafayette granite porphyry which is visible from Lafayette to Little Haystack, and on Mts. Liberty and Flume, and it outcrops on South Twin, around Galehead hut, and the Bond Cliffs. Finally, this brings on the formation of the Conway granite, which occurred as a subsidence down below the crust when huge blocks of the minerals described above melted, dropped into the cauldrons of molten magma forcing the lava higher into the crust where it cooled slowly. It's gradually exposed on the surface as a result of several hundred million years of erosion, particularly, but not exclusively, by the great ice sheets that slid by here during the Pleistocene Era, between 2.6 million and 12,000 years ago.

Does this look steep? It's a bit deceiving in the photo but it is inclined at a steep angle. The stairs were omitted in one section because it's possible hike up and down along both edges of the long escalator-like slab.

The Fishin' Jimmy Trail takes its name from Fishin' Jimmy Brook. The trail was designed and built by Paul Jenk, Charles Blood, and others between 1929 and 1930. You have to be impressed by the enormous amount of work involved when you see how rugged the terrain is, the steepness, and the amount of rock exposed. The trail became one of Paul's and Charles' pet projects, like the Garfield Ridge Trail that they opened together in 1914-1916. They had quite a bit of help in establishing the "line" which must have involved a lot of bushwhacking. At it's inception the idea behind the trail was recognition that Greenleaf Hut was under construction, the Lonesome Lake Cabins had been leased and were being used as a hut by the AMC so that the AMC Trail committee wanted to create more access to the Kinsman Ridge Trail and to create a direct link between Lonesome Lake and the Appalachian Trail to the south.

As often happens in the space of a few minutes a change in weather can occur. In this case it got very dark and rained a few drops just as I got back to the summit of North Kinsman.

The dark clouds cleared off and sun came out and with it any respite from the heat with the exception of the pond.

10-18-12 Mt. Lafayette: The Perfect Day.

This article has lots of photos that are a special gift to an extraordinary person and a mountain friend of many years, Charley Richardson, who is currently unable to hike and misses the mountains. Today the light was astonishing and the views from the summit were also astonishing. You could just see the top of the Eiffel Tower in Paris. Honest! See you soon, Charley.
When they say "follow your bliss", this is as close as I can get. Thursday the morning air was cold. I'd already hiked a few miles on a wild goose chase bushwhacking on Mt. Coolidge trying to get up Mt. Flume but, in defeat, turned my thoughts to summiting Mt. Lafayette. This was how the trail looked as I set forth. It was mid morning and the sun was just up over the ridge, and having escaped from the clouds, it had caught in the trees  turning the beech leaves into gold, and flickering, picked its way across the carpet of leaves setting them on fire one by one.
The Falling Waters Trail can be taken literally. I happen to dislike it for reasons I don't even remember, but it could never replace the Old Bridle Path so I hardly give it a thought. Falling Waters is usually quite busy as it's the first leg in the well used loop that goes up Little Haystack to Franconia Ridge at treeline and surfs along the high ridge to Mt. Lafayette, descends the Greenleaf Trail to Greenleaf Hut and continues down the Old Bridle Path to the car park. Of course, you can go clockwise and descend by the Falling Waters Trail if you like going against the herd.
Clouds that formed spontaneously over the summits and ridge from the warm air rising into the cold, upper air, filtered the sunlight, softening it, and created these warm brown tones in the leaf carpet.
Throughout the day the colors were rich and vibrant.
I stopped here on my way down in mid-afternoon to admire the late afternoon light caught in these same trees. The sun was low and in the west and the light slanted in from behind those trees in the background. The light shimmered as the wind rippled the beech leaves that are still clinging to the trees.  Ryan Adams has a song with the line, "I wish I was the wind, I'd touch your face." Standing in the soft wind and warm sun felt like being kissed.
It's lovely is all I can say.

A log that long ago fell here, and I remember it from 20 years ago, is still intact but slowly being hollowed out by termite larvae (worms) and waste material from all their chewing stands in a pile at the downhill end of the log. It will mix into with the older forest soil as a rich fertilizer.
Certified organic, locally crafted soil. One of the artisans is inspecting the new soil.
I used to tell the camp groups I was guiding up Lafayette to the hut that this was a giant's grave. Then, at night at the hut, I'd tell them ghost stories featuring the giant and they'd stay away all night. Then they'd be grumpy and difficult to keep moving on the trail the next day. It really wasn't such a good idea. Anyway, there are lots of ghost stories about the White Mountains. Some are true.
We used to call this section of the trail "Subway" because it was a trench that had been eroded by foot traffic and so deep that when you were hiking in it you couldn't see over the top on either side. The trail crew rerouted the trail in a few places and in others back filled the trench, like you see here, but it continues to erode.
In the December 1929 Appalachia, pg. 359, Paul Jenks contributed a piece, "Recovery of the Old Bridle Path on Mt. Lafayette", which is wonderful in many respects and a good read. The trail was first opened as a bridle path in June, 1852,  but had been used as a foot path as early as 1850. It was abandoned in the 1860s. Jenks and three other hardy souls set out in late summer 1929 to try and locate the old trail. Jenks wrote, "it was a great opportunity as may come to an amateur only once in a lifetime; (this is the man that helped open Garfield Ridge in 1914, 1915, and 1916) it was the last remaining problem of its kind in the White Mountains." p. 362 At any rate after a lot of bushwhacking and retracing of steps they were able to locate the entire length of the old trail and, with a lot of work, standardized it for use by the time Lonesome Lake hut was secured and construction of Greenleaf Hut was completed the following year.
First views of the ridge, Mt. Lincoln and Little Haystack (right) from the switch back at the low end of Agony Ridge. I should point out that the Old Bridle Path was cut and maintained by a local businessman, similar to the Crawford Path on Mt. Washington, to take sightseers to the summit of Mt. Lafayette beginning in the mid-1800s. They traveled on horseback up the same trail used by hikers today. A "hotel" on the summit, really just a rough, low cut building with windows, provided shelter and some warmth from the weather. The building burned leaving the stone foundation which can still be seen. Remember the stone foundation on Moosilauke? They're both relics of early attempts to turn a great view from a summit into cash. Mt. Washington, being the highest, was the most popular and the most civilized with a hotel that was a real hotel with comfortable beds. Franconia Notch with its alpine scenery and beautiful lakes was a popular vacation spot up to the 20th century. There were several large (huge), lovely hotels in the notch that were served by trains from New York, Boston, Portland and Montreal.
At the switch-back the trail hops up on this sidewalk-like ledge of Conway granite (or diorite) for the steep climb up on to the ridge.
The Conway granite has been intruded by this softer red granite that is more common over near Fryburg, ME. It's much softer than the Conway granite and as you hike up the ridge and pass several outlooks you will notice how crumbly the red rock is compared to the whiter Conway granite. In the photo the red granite is eroding from water runoff.

This is the intrusive red granite that has been weathered and sculpted by wind, rain, and freeze-thaw dynamics. This rock is weathering faster than the Conway granite....
that you see here..
that has also been weathered and sculpted by the same dynamics. These equally spaced "cleft notes" pose a mystery in how, exactly, they formed but wind, water, ice, etc. were the primary contributors. The photo below illustrates "quarrying"  where smaller blocks of the Conway granite break off larger ones. Some of them tumble down into Walker Ravine from time to time.

Quarrying with an artistic touch.
Looking up the agonies towards Lafayette's summit and part of the Walker Ravine headwall.
More of the enticing morning light where the trail climbs the 3 "agonies". There are actually 5 or possibly 6 agonies if you count all the bumps along the ridge to just below the summit, but only 3 are counted; the ones below Greenleaf Hut. The fourth agony is where the hut is located.
This character was a delight as were his two dogs. He explained how much he loves hiking and being in the Whites and said he had gone out west to try the hiking out there but had to leave his dogs at home. "I couldn't do it," he said. "I missed my dogs too much." So he came home.
The Agony ridge takes it's name primarily from people like the lucky mean and women who work work at Greenleaf Hut each summer and have to carry all kinds of interesting things up it and down it. The photo shows the bottom of what we call the "first aggy" or first agony. It's also referred to as "Red Rock" because of the color of the surficial rock which has a high iron content. It's very slippery when its wet and not much fun to pack up with excessive loads. The last time the Old Bridle Path,was used by four legged animals was back in the early 1960s when the AMC used to own a string of pack mules that were used to bring in what we called the "initial" which was the heavy canned food goods. The mules were around for 20-25 years. A lot of those initial supplies that are used to get the hut up and running at the beginning of each summer, including the propane gas, is now brought in by helicopters. Hut croos pack the "fresh" (foods) and additional supplies throughout the summer.  If and when you hike up this 30 yard stretch of trail think how they got a horse to climb up it. They did it by a little trick which was to hand line the horses around red rock on the Walker Ravine side of the ridge on a solid ledge of Conway granite that had steps for the horses made of wood and held by iron bolts cemented into the granite. You can still see the bolts.
This is the slippery part of Red Rock. In pouring rain it's a good scramble.
This is the top of White Rock. The horses had to climb steeply along the edge of the ravine to reach this spot and rejoin the trail. I would imagine the riders got off the horses and walked this.
The woods on the west side of the trail. The ridge drops steeply and a 100 feet down becomes a cliff that drops down into Franconia Notch.
He left the highway early and is doing the Franconia Ridge Loop. He said the ridge was cold and windy.
This meadow-like place on the trail and just below the hut is a measuring stick for balsam fir growth. I've kept track of it for more than 5 decades and remember what it looked like, say, in 1961 when it was twice the size it is now. I used to refer to it as an "alp" and wanted to bring a cow up for the summer so we could have fresh milk.
Greenleaf Hut shuttered for the winter. It closed for the season two weeks ago in late September. It's nickname is The Flea. All the huts have nicknames. Galehead Hut is Ghoul, Zealand Falls Hut is Zool, Madison Hut is Chez Madison or Madhaus, Lakes is simply Lakes, or used to be, Mizpah is The Pah, Carter is Cata, and Lonesome is Lonesome.
I was reclining and basking in the ample sun on the porch when a couple of hikers appeared who had obviously been camping by the looks of their packs and had come down off the summit. Two young men came along first, introduced themselves and asked about water. It turned out that they were from the outdoor club of Haverford College in Pennsylvania and had been on their fall camping trip. There were a total of 30 students on the trip but they had divided into two groups of 15 students.  Fifteen went east from Franconia and 15 came west from Crawford Notch and they passed each other somewhere in the middle.

 They kept arriving.....

and flopping down...(the great pleasure of unburdening yourself of a heavy pack one's been carrying hour after hour and being able to collapse on the ground or a warm, flat rock).


                                                                       and arriving....
That morning they had hiked over from the Mt. Garfield tent site, about 5 miles, and were low on water. There's no water available at Greenleaf Hut when the hut is closed. There is a spring but it is on the north end of Eagle Lake and nearly inaccessible. The students decided to filter water from the lake to fill water bottles. Inertia caught up with this student and she instantly fell asleep on the comfortable rocks.

I like to see groups of students, teens, or young kids in the mountains, with their families, school groups, summer camps, etc, because I see them (and treat them) as the "next generation", the ones who hopefully will come back time and time again and eventually bring their families here and, in time, take an interest in preserving the knowledge, the memories, the love and the respect for these mountains that earlier generations have preserved for them.
This gleeful young man is from Sherbrooke, Province of Quebec (PQ) or, as they say in Quebec, the "Eastern Townships". He had arrived in the morning and we met by chance in the parking lot. He opted to take the Falling Waters trail to Little Haystack and then head north over Franconia Ridge to Lafayette and descend from there. We were supposed to meet in the middle of the ridge but I was dawdling and stopping to take photos so we passed each other on Lafayette.

No one's belted me yet when I've asked to take their photo. She was a little reluctant but took a nice picture anyway.

 and her husband was obliging as well.
There were all kinds of characters out and about.
Texting into the wind.
The summit! The reward for all the labor: this exquisite view across New Hamphsire into Maine, Vermont, New York and Quebec, Canada. Mt.Washington and the Presidential Range are in the background, North and South Twin the dark, middle ridge with Guyot and Bond further to the right, and  Mt. Garfield in the foreground on the left.
Looking due north over Lafayette's north peak. You can see the Pilot Range and for some reason the Percy Peaks are hidden. Mt. Sutton in Quebec is clearly visible.
Looking northeast with Adams and Jefferson of the Presidentials on the right in the medium distance. You can also clearly see the Mahoosucs in the far distance with Old Speck and Goose Eye visible. In the center of the photograph is Mt. Cabot surrounded by the Kilkenny Wilderness and to the left is the Pilot Range again. Cherry Mt. aka Mt. Martha is in the center of the photo in the middle distance. North Twin is behind and to the right of Garfield which is in front with the cliffs.
The light was intense and the colors amazing. Looking east at Mt. Washington over the Twins with Garfield to the left and, in back, Guyot and Bond. In the back row, right is Mt. Kearsarge. In the back row, left is the Mahoosucs.
Mt. Washington to the left, Mt. Carrigain on the right.
Looking southeast at Mt. Carrigain on the left, Mt. Flume on the right in middle distance (at the end of the ridge). In the middle, to the right of Carrigain are the Hancocks, and Osceola. In the distance, left to right, are the Ossipees, Passaconway, Whiteface, Sandwich Dome and Tecumseh. Nice photo!
Looking South towards Lincoln and Flume with the Sandwich Range to the left. Thursday morning, to research the feasibility of the Pemi Traverse I've been hinting that I might try, I bushwhacked up Big Coolidge mountain north of the town of Lincoln to see if there was a possible line from there to Flume but it was dense conifers, so dense it would take the fillings out of my teeth if I tried crawling through it. However, there's an abandoned trail running from the Kancamagus Highway up to Flume that skirts the east side of Mt. Osseo (or Whaleback) and that might be a bushwhack legitimately since it's been abandoned 40 years. I want to check it out and see, first, if I can find it, and, two, if it's passable.
Looking west to Moosilauke and the Kinsmans with Sugarloaf in Vermont in the background.

 Getting towards the bottom of the ridge and the end of a lovely day.

On the way down from the ridge I passed a young woman who was coming up the trail and who asked if I had seen two "older men" heading up and I said that I had and had checked with them how far they were planning to hike explaining that it was getting late to try for the summit. The men were congenial and thanked me for my concern. The young woman explained that they were friends of her father's and they'd all been hiking together but her father's health was not good. As she described her father's declining health she was overcome with grief and expressed the fear that his illness was serious and, if it was true, he would never climb Lafayette again, or hike again. Her grief was palpable and standing there on the trail I felt terrible for her and her father, of the loss that is inevitable and the pain that will come with it. Her dad and I are the same age and I thought about my daughters. It brought up my denial about what could happen to me and it's impact on my family. I identified with the young woman and her father both. So, I want to say to her how much your candor and openness affected me and how sorry I am for your loss and the painful changes lying ahead, and, most of all, I want to say thank you.
