The Sideling Hill road cut is a 340-foot deep notch excavated from the ridge of Sideling Hill for Interstate 68, about 6 miles west of Hancock in Washington County, Maryland. It is notable as an impressive man-made mountain pass, visible from miles away and is considered one of the best rock exposures in Maryland and the entire northeastern United States. Almost 810 feet of strata in a tightly folded syncline are exposed in this road cut. Although other exposures may surpass Sideling Hill in either thickness of exposed strata or in quality of geologic structure, few can equal its combination of both. (This and next two photos.)
