Numerous, diverse features and observations point to the progressively increasing penetration of meltwaters beneath the ice sheet and its progressive warming. As is now well known, the distinction between Warm versus Cold ice is important as it relates to Glacial Dynamics. As noted above, Ice Marginal Channels represent warming of the basal fringe of the ice sheet, beneath cold ice. And the absence of such Channels in T7 and Fort Ann and then in Champlain Sea time is regarded as an indicator of the ice becoming fully warmed. Other features as well provide evidence of warming, all in a late glacial T7 , Fort Ann and then Champlain Sea time. The Shattuck Mountain Pothole Tract likely represents meltwater penetration to the base of the ice sheet, with its formation under confined hydrostatic head conditions, showing the increasing presence of substantial meltwater at the base of the ice sheet at a late T7 and Fort Ann time. Similarly, the spillway at Oak Hill strongly suggests drainage associated with Lake Mansfield 2 via a subglacial tunnel in late T6 and early T7 time. And a large deposit nearby in the Williston area mapped by Stewart and MacClintock as “Wave Washed Till” is here instead regarded as drainage of Lake Mansfield by widespread, dispersed seepage at the base of the ice sheet at the same time. Similarly, basal gravels as reported by others in The Middlebury, Monkton, and Charlotte areas likewise suggest such basal ice water presence. Scarps which are interpreted as lateral shear margins of later T7 ice streaming are closely associated with a peculiar till containing an unusual amount of rounded pebbles, which again represents subglacial drainage with associated deposits incorporated into till at shear margins. Taken together, these observations are all indicators of ice warming ad basal meltwater, which represent an especially important Glacial Dynamic.
