Stebbins Gulch Potholes

Potholes in the Berea Sandstone, above the “Big Falls.” 

Potholes are formed by the constant swirling of water laden with sand and small pebbles.  They are closely related to plunge pools that occur beneath waterfalls.  The sediments act as an abrasive, eventually boring a hole into the rock.  Look for them on any stream bottom floored with siltstone or sandstone.   Depending on the type of rock and velocity of the stream, some potholes can grow to several meters in diameter and depth.  Those at Stebbins Gulch rarely exceed a foot or two in diameter, and may be fairly young, because the surrounding rock has only recently been exposed to erosion.  Larger ones occur in the unglaciated areas of southeastern Ohio.
