Lost In The Wilderness - Part Five

This is the fifth in a series of posts on the Beaver Kill Ravine.

Aside from the presence of the old brick and stone culvert giving a glimpse of a rushing river beneath the Lincoln Park gully, my other favorite feature of the Beaverkill ravine is the stone. The north and south walls of the gully are lined with heavy gray-black outcroppings of truly ancient bedrock.

According to a geology report in a 1930 bulletin from the New York State Museum, the stone is "Snake Hill shale" which it describes as a "dark, argillaceous, intricately folded and crumpled, as much as 3,000 feet deep."

According to the same 1930 report, there are very few places around Albany where this ancient bedrock lies exposed. I've seen similar stone along the Normskill near Delaware Avenue at the City's southern boundary. The other location given in the bulletin is a spot called Black Rock Cut, somewhere along the old NY Central Tracks near Tivoli Lake.
