The Tucson Mountains lie in southeastern Arizona and occupy a large part of the eastern half of the Langhorne quadrangle, between latitude 32º00' and 32º30'N. and longitude 111º00' and 111º15'W. The range trends about NNW and is bordered on the eastern side by the shallow Santa Cruz Valley and on the west by a similar valley locally called the Altar, Avra, or Abra Valley. The city of Tucson is located at the east base of the central part of the range. The range is 25 miles long and about 10 miles wide in the central part, narrowing toward both ends.
The range consists of a series of folded and thrust-faulted Paleozoic and Mesozoic sedimentary rocks, upon the eroded and peneplaned edges of which lie a series of Tertiary effusives. A great thrust fault which can be traced almost the length of the range was nearly obliterated by the erosion which left the overthrust block represented by a multitude of small klippen on the pre-volcanic surface. Post-volcanic block faulting, tilting of the composite mass toward the east, and erosion have given rise to an escarpment along the western side of the range and a dip-slope on the east. Large intrusives in the west-central part, and transverse as well as longitudinal faulting throughout, have added to the complexity of the structure of the range.
