While we were waiting for this fellow to cross the trail (in NOVEMBER?!), I heard something making a racket down in the gully next to, and it was a second tortoise. I've never seen two of these guys in the same place, or any this late in the year before.
A @peregrinefund volunteer hazes a California condor on the Navajo Bridge at Marble Canyon. For their own safety, it's important these massive birds (3 meter wingspans!) don't get comfortable perching on the pedestrian bridge.
