NM 485 becomes a one lane road as it enters Rio Guadalupe Canyon, so we parked on a wide pullout about 1/4 mile from the mouth of the canyon, and walked along the edge of the road into the canyon. After photographing the “Falling Rock” sign, I turned around to find a humming bird moth working the flowers in the brush behind me. The first guardrail along the road was covered with graffiti.
