TheAtascosa Mountains is a mountain range in westernSanta Cruz County,Arizona, United States.[1] It is sandwiched between the largerTumacacori Mountains to the north, and a small east–west border range to the south, the Pajarito Mountains; the Pajaritos are on the U.S.–Mexico border and abut theSierra La Esmeralda range in northernSonora.
The Pajarito and Atascosa Mountains are the central ranges in theTumacacori Highlands.[2]
The highest peak is Atascosa Peak at 6,440 feet (1,963 m); adjacent to the northeast is Ramanote Peak, 6,047 feet (1,843 m).Pena Blanca Lake on Ruby Road, arising from the lowest elevations of Calabasas Canyon–(tributary to the Santa Cruz River) are part of the Atascosa's southern border. Ruby Road continues beyond the west of the Atascosa's and Peck Canyon Road borders the north, but accesses highest elevations in the ranges' center and north.
The Tumacacori Highlands is a series of connected mountain ranges in western Santa Cruz County. The Highlands are northwest ofNogales and are bordered on the east by theSanta Cruz River Valley, that is traversed north–south byInterstate 19. Across the valley eastwards are the tallSanta Rita Mountains in the northeast, and the smallerSan Cayetano Mountains, east and adjacent to Nogales's northeast. The sequence of the north-to-south Tumacacori Highlands is as follows:
North to south:
A Santa Cruz county-border "bootheel" extends southwest; the bootheel contains Cobre Ridge, and it is connected northwest to a small range, theSan Luis Mountains which are in the southeast of theAltar Valley, and borders theBuenos Aires National Wildlife Refuge.
Historical mission communities, atTumacacori National Historical Park, inTumacacori, lie at the southeast foothills of the Tumacacori Mountains.
