Large Scale (1 to 4000) Photos of Till and Peat

The first anaglyph shows the elevation differences that are assocoated with the cloud-like gray tone pattern observed with young clay tills. Wind erosion of the more organic top soils from the slightly higher knob tops leaves them a slighlty browner color than the lower lying more organic and darker soils. The second anaglyph shows a peat deposit formed in a eutrophying pond. This region can be recognized by the vegital gray tone of the marshy plant life at the boarder of the low lying area. Organic peat deposits can be found within all glacial deposits where kettles have been formed. These small ponds are undrained and gradually eutrophy as dead organic matter gradually replaces the water. Their growth is shown in the cross section and plan illustrations (Sowers, 1978). Home
