Tracks in a well traveled arroyo of Saguaro National Park West. Tracks were less than 7 days old (deposited after a rainfall event on Jan 28/29, 2021). Trackset was long and well defined, consisting of over 100 prints. Animal headed upstream, generally west.

Track set in Tucson Mountain Park, at urban interface. Tracks headed down an arroyo, heading northeast. Track age difficult to establish because of the coarse substrate: estimate more than 2 days old, but less than 1 week. I suspect this is the same animal that I observed tracks from, in a nearby arroyo (on the other side of the ridge). Track characteristics were undeniably typical of P. concolor: three lobed plantar pad, asymmetrical toe layout, gap between toes and pad forming the typical "C" shape.
