In the Pleistocene, in the age of Elster and Saale glaciations, the continental glacier penetrated the area from the north, followed by depositing of glacial and glaciofluvial poor-graded gravelly and sandy sediments of a brown, grey-brown, yellow, or reddish colour, and glaciolacustrine sediments, represented by grey-reddish, grey-brown, or reddish-brown clays and sandy clays, laminated in grey and with sandy lenticulars in places.
Until 10,000 -15,000 years ago, it lay beneath the Wisconsinian continental glacier. When the glacier receded, it melted first in the rolling uplands, strewing it with flat rocks wrenched from the horizontal Devonian formations of shale and sandstone.
My association with those scientists was during my graduate studies, which involved evaluating the advance and retreat of the last continental glacier on North America some 14,000 years ago.
Also, many of these studies have been carried out in mountainous regions where the hydraulic head and thickness of the ice may have been much greater than it was here, at the very margin of a wasting continental glacier. And finally, it appears that the large-scale and complex features seen elsewhere connote repeated channel formation beneath very active glaciers, whereas it seems likely that the N-channels on Flat Rock were the result of a single short-lived episode of erosion at the distal margin of a waning ice sheet.
Instead, it has a two-mile-thick mass of flowing ice called a continental glacier. "Ice is the overwhelming physical presence in Antarctica," Wu says.
At the end of the last ice age, continental glaciers reached 300 to 400 miles north of where my house now stands in central Virginia.
