Near Hancock in Washington County, Maryland — The American Northeast (Mid-Atlantic)
Sideling Hill Cut South Bench
Across the highway, you have a clue to the past. The slanting tan sandstone was the bed of a river which scoured out the curved place you see. The river meandered away and left a marshy area or lake which was filled with dark gray mud or claystone. This cut-off is called an oxbow or buried stream channel.
The Monocacy River south of Frederick is about the size of the river which made this channel.
