Piedras Marcadas in Albuquerque, NM

Piedras Marcadas sits on Albuquerque's Northwest Mesa in the 87114 ZIP code, along the basalt escarpment that carries Petroglyph National Monument through the city's western edge. The neighborhood shares its name with the canyon beside it, Spanish for marked rocks, which the National Park Service describes as the monument's densest concentration of images, roughly 5,000 documented along a 1.5-mile round trip. That trail is undeveloped, with no facilities and sunrise-to-sunset hours; the trailhead sits on Golf Course Road, reached from Jill Patricia Street south of Paradise Boulevard. The city recognizes a neighborhood association for the area.

The canyon along the neighborhood's edge is protected city Open Space, managed by Albuquerque's Open Space Division within the national monument. Parking is a small lot called Las Marcadas rather than a visitor center, and the route stays a dirt path at the base of the escarpment.
