Unit 33
Tucson
Desert basins and rolling foothills rise into sky islands where multiple ranges create a complex patchwork.
Hunter's Brief
Unit 33 spans the country between Tucson and the San Pedro River—a mix of low desert scrub, rolling bajadas, and scattered mountain ranges separated by broad basins. The Santa Catalina and Rincon Mountains dominate the landscape, with elevations jumping from desert floor to high-country ridges. Access is good via highways and developed roads, but the terrain complexity means knowing where you're going matters. Multiple species are present across different elevations, making this a diverse but demanding unit.

Terrain Deep Dive
Landmarks & Navigation
The Santa Catalina and Rincon Mountain ranges dominate glassing and navigation. Tanque Verde Ridge, Pusch Ridge, and Organization Ridge provide backbone routes and vantage points. Notable named basins like Molino Basin, Happy Valley, and Burro Basin serve as travel corridors and natural congregation areas.
Stratton Saddle, Happy Valley Saddle, and The Narrows are key passes for movement. Mount Lemmon Air Force Station and Summerhaven mark high points. These features are recognizable from distance and valuable for orienting yourself in complex terrain.
Elevation & Habitat
Terrain ranges from low desert valleys around 2,300 feet to high ridges exceeding 9,000 feet, creating distinct habitat bands within relatively close proximity. Low-elevation country is sparse sagebrush and creosote desert, transitioning to juniper and oak woodlands on bajadas and lower slopes. Higher elevations support dense ponderosa and mixed conifer forest on the Catalina and Rincon ridges.
The elevation jump creates natural funnels and corridors—animals move vertically through seasonal ranges, making elevation understanding critical to hunting strategy.
Access & Pressure
Over 1,300 miles of roads crisscross the unit, ranging from well-maintained highways to rougher forest roads. Arizona 77 provides main access; secondary routes branch to lower elevations and into major drainages. The connected road network means access is fair throughout, but terrain complexity keeps some country less pressured.
Popular areas near Tucson and along main ridges see concentrated use, while backcountry basins and upper drainages offer relief. The unit's size and complexity mean hunters can find less-hunted country, but they need to work for it.
Boundaries & Context
Unit 33 frames the area east and north of Tucson, bounded by the San Pedro River on the east, Interstate 10 on the south, and Saguaro National Park and Coronado National Forest on the north and west. The unit encompasses rugged mountain ranges and wide desert valleys in central Arizona's transition zone. Tangerine Road and Arizona 77 form key boundary references.
The terrain encompasses the Santa Catalina and Rincon Mountains along with intervening desert basins—a vast area with significant elevation change and distinct geographic zones.
Water & Drainages
Reliable water is scattered and seasonal. The San Pedro River borders the unit on the east—a major drainage. Sabino Lake and several named tanks (Gap Tank, Cement Dam Tank, Stratton Tank) hold water when reliable, but availability varies with monsoon patterns.
Named springs like Finger Rock Spring, Cherry Spring, and Apache Spring exist throughout but require local knowledge. Washes like Turkey Creek, Redrock Creek, and Peppersauce Wash flow seasonally. Water hunting here demands knowing which tanks are currently reliable—critical intel before planning your route.
Hunting Strategy
Unit 33 offers multiple species across distinct elevation zones. Mule deer and white-tailed deer occupy both low desert washes and high-country ridges—elevation drives movement seasonally. Elk inhabit the high mountains, concentrating in the Catalina and Rincon ridges during hunts.
Pronghorn are found in open basins below the forest line. Mountain sheep and desert sheep use cliff country and steep ridges—glassing distant slopes from vantage points like Tanque Verde Ridge or Organization Ridge is essential. Bear and mountain lion are present throughout.
Javelina occupy lower scrub zones year-round. Success requires understanding which species uses which zone and when elevation influences their movements.
