The Adirondacks showcase many lessons in ecology, earth science, and a legacy of the human impact. Some 18,000 years B.P. glaciers had moved across this wilderness we recognize as Adirondack Park. One glacier excavated bowl-shaped cuts in the side of Whiteface Mountain. Another glacier from the north shoveled sand and gravel from an area now know as Potsdam, trucked it 30 miles south and deposited at a higher elevation on the north slope of Whiteface. Another glacier is responsible for the boulders thrown in front of my walk up Blue Mountain at 4:30 A.M. These boulders have seen life from somewhere in Canada, survived the migration of entire ecosystems over their surface, and now they serve as a refuge for insects, the beginning of life for mosses, rock ferns, and a yellow birch or two.
Fifteen minutes into the walk, the morning chorus begins with a Swainson’s thrush, and then a second, and a third. Their bubbly crescendo introduces our ears to a new day. It is still dark and our flashlights are illuminating the rock strewn trail. Shortly after the Swainson’s started, the smooth clear notes of the white-throated sparrow introduce themselves to the new day. It has been reported that the larger birds with big eyes begin the morning chorus followed by the singing of successively smaller bird species. This trend continued with the Blackpoll warbler, Tenneessee warbler, and the winter wren on our ascent.
The change in eleveation along the trail shows another interaction between earth science and biological ecology. Trees typical of a temperature deciduous forest (American beech, eastern hemlock, yellow birch, and sugar maple) throughout New York are observed at 2000 ft where the trailhead begins. Somewhere around 2800 feet balsam fir and paper birch become more common. The forest is shorter here and the trees are sculptured by the wind, long winters, and drier conditions. In terms of appearance, the higher elevation fir-birch forest looks like the impoverished neighborhood on the mountain. Thin soil, dry conditions, and severe winters keeps these trees from reaching their full potential.

Aside from the breeze, the top of Blue is silent except for a dark-eyed junco singing somewhere on the tree line. We skirt around the rock escarpment carefully listening for another, much rarer thrush called Bicknell’s. This bird is the sole reason I encouraged my son, Cory, and my friend Tom to the top of Blue so early in the morning.

Cool post Steve. I'll be posting my thoughts on our trip shortly. I'm off to Albany today to play golf with Brendan and Dave (two old friends you met at my 50th. I'm going to tell them Corey is my "swing coach."
How about "awaiting our stiff-but-anxious bodies?" I know I don't loosen up until about 15 minutes in.
