So if you go to this particular location, I can't promise that you'll find a melanistic Round tailed ground squirrel like I did, but I can promise that you'll see Round tailed ground squirrels and good amount of them. From my observations, the best place to find this species in large numbers in Pima County is at Brandi Fenton Memorial Park near the Catalina Foothills across the street from the Tucson Jewish Community Center. I used to do martial arts training in that park.
