Unit 46A

Key navigation markers include the Agua Dulce and Growler Mountains, which provide visual reference points across the flat expanse. Granite Mountains and Sheep Mountain offer higher vantage points for long-range glassing across the valleys. Multiple passes—Cholla, Charlie Bell, Saguaro Gap, and Temporal—funnel wildlife movement and mark natural travel corridors.

Scattered summits like Scarface Mountain and Papago Mountain serve as orientation points. These landmarks are critical for navigation in a landscape with limited roads and vast open distances.

Terrain ranges from below 1,000 feet in the desert valleys to just over 3,200 feet on the isolated peaks, creating a low-elevation desert ecosystem with sparse vegetation. The landscape is predominantly open desert with scattered mountain ranges rising abruptly from flat basins—islands of slightly higher elevation in a sea of sand and creosote. Vegetation transitions from pure desert floor to rocky foothills with occasional juniper and palo verde.

This is not forested country; expect open views, minimal shade, and an unforgiving thermal environment.

Access is intentionally restricted within the refuge—only 37 miles of maintained roads service the entire unit, creating extremely low pressure and genuine solitude. No major highways penetrate this area, and no developed towns sit on the boundary. This is backpack country where hunters arrive at the refuge boundary and proceed on foot.

The limited road network actually protects the unit from casual hunting pressure, but it demands serious preparation: pre-positioned water, reliable navigation, and self-sufficiency.

Unit 46A encompasses the eastern portion of the Cabeza Prieta National Wildlife Refuge, a sprawling protected area managed for wildlife conservation. The Yuma-Pima County line forms the western boundary, with the refuge extending eastward across some of Arizona's most remote desert terrain. The unit is vast despite minimal road infrastructure, creating a landscape where distance and isolation define the hunting experience.

This is federal wildlife refuge country where access is controlled and foot travel dominates the hunting approach.

Water availability defines every hunt in this unit. Tanks are the lifeline—Redtail, Pozo Salado, Parra, Little Tule, Jose Juan, Antelope, Granite Pass, Bassarisc, and Sheep tanks are scattered throughout. Agua Dulce Spring provides a reliable water source.

In this limited-water environment, wildlife congregates around these features, especially during dry months. Understanding tank locations and seasonal reliability is non-negotiable. Most tanks are seasonal or dependent on rainfall, requiring current local knowledge before committing to a hunt.

Unit 46A supports diverse species adapted to low-elevation desert: pronghorn, mule and white-tailed deer, desert bighorn sheep, javelina, mountain lion, and occasional elk and bison. Pronghorn and desert sheep are primary species in this terrain. Hunt around reliable water sources, especially tanks, during warmer months when animals must drink regularly.

Glassing from elevation points works well across open terrain. Arroyo bottoms like Deer Hollow and Davidson Canyon funnel wildlife during movement periods. Expect extreme heat and minimal water—this is physically demanding desert hunting.
