I know this area of the Atascosa Mts. quite well. It has some interesting geology and some hidden pictographs — but no one explores there anymore. The same holds true of the Ramanote Canyon just to the north, and the former birding sites at Walker Canyon and Sycamore Canyon that are found west of Nogales and which run north-south across the US-Mexico border. In the last six months Peck Canyon has been the scene of numerous clashes (including exchange of gunfire) between coyotes of one Mexican gang and another gang involved in the movement of narcotics, whores and illegal into Tucson. Believe me, it is the wild west, and I feel sorry for the people at Peck Canyon ranch who live at the entrance to Peck Canyon itself. Recently, the situation has become so tenuous that the Chief of Police in Nogales has ordered his men to be armed 24/7. Across the border in Nogales, Sonora, the Deputy Chief of Police was assassinated, and the police are running scared. Real scared. Meanwhile, the commerce of Nogales, Mexico, which used to be a pleasant tourist destination only two years ago, is dying.
