Description
Avra Valley is a narrow valley, only about 10 miles wide in some locations, and bordered completely on the west by low elevation, arid mountain ranges. From the northwest, the mountains are the West Silver Bells, Silver Bell Mountains, Watermans, and then in the southwest the Roskruge Mountains. South of the Roskruge, Arizona Route 86 enters the valley from the Tohono O'odham Nation to the west. Robles Junction, Arizona, is also in the southwest, at the junction of the valley going southwest to Sasabe, the Altar Valley. Robles Junction is also at the northwest of the mountain range on Avra Valley's southern border, the Sierrita Mountains.
The north of the Avra Valley narrows at the Silver Bell Mountains and Marana to the east. The region merges into the wider flatlands associated with the floodplain regions of the northwestern Santa Cruz River where it begins to merge with the Gila River.
