Unit 35B is northeast of the busiest Mexican border crossing in Arizona, Nogales. Hunters in the Patagonia Mountains take some mature Coues deer. Cover is moderately dense, but hiking is not overly strenuous. Antelope are so scarce that no tags are issued.

Some of the finest Coues deer hunting in the state takes place here. Desert mule deer also inhabit this unit with few big bucks.

Low grasslands and Sonoran desert are found at low elevations. High ground is comprised of canyons, rocky hillsides and steep, rocky slopes. Terrain is moderate and not considered strenuous.

Lowlands are Sonoran desert with desert scrub, cactus and grass. Middle-elevation terrain is a mixture of desert grasslands, oaks, pinyons and junipers. Oak and manzanita grow in the high mountains.

Most land is in Coronado National Forest. Private land prevents access in some areas. Hunters need to get a landowner’s permission to cross some private tracts to reach public property. Just north of the Mexico/Arizona border is the private San Rafael Cattle Company, which is closed to hunting. It is shown on some maps as San Rafael de la Zanja.

Camping is allowed on Coronado National Forest lands. Lodging is in Nogales, Sierra Vista, Patagonia, Sonoita and Tucson.
