Text On Markers:
The view from this point reveals the effects of major glaciation in its most vigorous form. Some 10,000 years ago, the last glacier, as it receded slowly to the north and west, paused here long enough to deposit, in characteristic fashion, the rock material in the recessional moraine that forms the hills around Lake Minnewaska. The basin of the lake is chiefly within the moraine itself, but on this, the northeastern side, it is bounded by an extensive outwash plain.
The part of the glacier that filled the lake basin be-came detached from the main body of ice and remained stagnant for many years. During this time it was partially or completely buried by outwash sand and gravel carried toward the northeast by meltwater from the main ice field. As a consequence, this portion of the basin had a steep ice-contact slope, formed while the ice block supported the loose material.
Lake Minnewaska, lying 230 feet below this elevation, is a typical example of a lake in an ice-block basin.
