The hills around Cannonsburg are glacial leftovers, sand and gravel heaped up and then left to grow oaks, and in winter their west faces catch every band that comes inland. Cannonsburg Sand & Gravel turns to snow removal once the ground locks up, plowing drives and lots through that hill country east of Rockford. A sloped driveway has to be taken from the top down, in bites, so the pile never gets ahead of the truck. Ice matters more than depth out here — a north-facing grade can stay slick two days after the last flake. When the hill lights come on in the early dark, the pavement below them is bare and the way out is open.
