Sipping from rock once fuming and flowing
Drawing from deep water pebble-pimpled silt,
Splitting muck-mired cobbles of glacial mowings
Benefacting cycles of rise and wilt...
This forest chews lava, and exhales the whispers of glaciers...
The forest along the upper portion of the trail is truly unique, as it is dominated by linden, ash, and cucumber magnolia. The great number of seeps along the trail provide for excellent exploration and the make-up of the forest shifts around every corner!
Here's a small bit of what we saw:
Geology:
Rock type #1, near the beginning of the trail, is :
Konnarock Formation; Maroon diamictite, rhythmite, and arkose. These are rocks that were deposited in habitats that included deep icy lakes and glacial activity. They are the silicified (fancy word for 'turned into rock') remains of muds, silts, pebbles and cobbles carried by glaciers. Interestingly, the stones seen in the silicified mud were dropped into that muck and consist of materials from formations nearby...ryholites, greenstones, and granites. This makes sense because the glaciers would have been eroding these materials from the land during that time...and, it was a landscape devoid of plants and animals!...mountains and valleys of pure rock, silt, and sand!
