Beaver dam #3 in the chain, Zealand Valley, September 2, 2008

This is a relatively old beaver dam probably dating from the 1970's. It has captured mud (soil) and is overgrown with plants including a birch sapling. To the right and downstream from the dam you can see the silt build up and the plant life taking over the channel. This means the flow rate of the stream in very slow for most of the year and that beavers are no longer active here.

About this Blog

White Mountain Sojourn offers an accessible and hopefully exciting way to interact with the landscape and the richly diverse natural history of the White Mountains of New Hampshire through a series of “snap shots”. These snap shots will include photos, research articles, and some personal observations from folks that work in and/or spend a lot of time in the mountains as well as observations provided by you (the readers). These snap shots will focus mainly on the natural history of the Whites during the past 10,000 years, or so, and they'll have the potential to show the subtle as well as dramatic changes in the natural history of the White Mountains over that period of time. The idea is that we often look at our landscapes from a single dimension of time, namely the immediate present, and then miss a lot of what is really going on there. The exciting part can be returning time and time again and seeing and understanding what goes on when we're not actually looking. The White Mountains are also a back drop for myriad human activities that took place all those thousands of years. White Mountain Sojourn will also be looking at some of the changes occurring at the present interface of human activity within this wild, beautiful forest ecosystem.

A little more about the author

I grew up in the White Mountains of New Hampshire. I lived in Intervale and North Conway, NH, from the late 1940's to the late 1950's. In 1961 I started working for the Appalachian Mountain Club as "croo" in the huts and eventually as a guide and naturalist. I continued working for the AMC during my college years. I took an inordinate amount of time to finish my undergraduate studies in plant ecology. To make it look like I was being productive I began writing what I hoped was an impressive-sounding Ecology of the White Mountains. With that grandiose title I received some useful notoriety but the problem was that I never really wrote anything. I kept up a facade the secret of which was just to act really cool. I pretended to be busy with small research projects that were supposed to relate to my Magnum Opus. One was titled "Comparative Frost Hardiness in Two Species of Larch." It was ingenious if only because it allowed me a great deal of free time during the warm months. I did manage to help others finish their research projects. I assisted L. C. Bliss for a while as he put together his brilliant Alpine Zone of the Presidential Range and also helped my friend and colleague Larry Collins with his limnological study of the alpine lakes of the White Mountains. So, to bring you up to date Ecology of the White Mountains is still unfinished--a collection of musty, dog-earred notebooks just itching to get done--if only for old time's sake. So come along while I get it out of the box and rethink and redesign it. You can help by adding your thoughts, articles, insights, photos, criticism, etc. We can revisit every mile of the "Whites", bask on the summits, run down the trails, delight in the beauty.
