Our wooded property borders a ten-acre nature preserve shared in a homeowners association and adjoins additional private acres, mostly wooded backyards, that comprise the ravine. The land is in various stages of recovery after human impact, so there are overgrown remnants of pasture and cropland, old cattle tanks, a small public park, and some steep rocky slopes immune to commercial land gobblers. For me, this place is a small part of prehistory and a much larger exhibit of how humans change living landscapes.
