A Winter Drive
On a blustery January weekend, we packed our bags and headed west from Baltimore on I-70. We passed Frederick, passed Hagerstown, and just kept driving, with only a vague notion of a destination somewhere in western Maryland. On the far side of Hancock, we turned onto I-68 and approached the man-made mountain pass called Sideling Hill, one of the best geologic exposures of rock in the northeastern US.
