Mule Deer Hunting in Unit 18B

Where to Find Mule Deer in Unit 18B

Unit 18B mule deer inhabit the Sonoran desert bajadas and foothill ranges northwest of Phoenix.

Hieroglyphic Mountain Bajadas (2,500–3,500 ft)

The broad saguaro-studded bajadas around the Hieroglyphic Mountains concentrate deer, especially near stock tanks and along wash corridors. Glass from high points along Castle Hot Springs Road.

Hassayampa River Corridor

Deer use the riparian thickets and surrounding upland desert as cover. Hunting within 1/4 mile of the river is high-percentage at dawn.

Stock Tanks and Catchments

Scattered windmills and earthen catchments across BLM land concentrate deer in dry seasons. Pre-scout active tanks and set up afternoon ambushes.

How to Hunt Mule Deer in Unit 18B

Unit 18B is classic desert mule deer — glass hard, hydrate harder.

Dawn Glassing

Pre-dawn setup on a bajada ridge with tripod and 15x spotting scope. Grid slowly across the cholla-grass flats and along wash edges. Deer stand out in the low, bright desert morning light.

Wash Walkthroughs

Mid-morning, still-hunt down shaded washes where deer bed. Go slow, use the wind, and ease through mesquite bosques.

Tank Ambushes

In dry years, evening setups at active stock tanks produce reliable buck encounters. Scent control matters — desert deer have sensitive noses.

How to Hunt Pronghorn in Unit 18B

Unit 18B is a classic vehicle-glass-and-stalk pronghorn unit with good road access across the mesa country.

Mesa Road Network

Drive the mesa-top roads slowly, stopping at every rise to glass. Pronghorn in open country are visible from miles away with quality optics.

Terrain-Feature Stalks

Use shallow washes, road cuts, and PJ edges to close distance. Pronghorn eyesight remains the primary challenge — maintain cover and move only when heads are down.

Water Ambush

Active stock tanks produce consistent afternoon opportunities. A ground blind or natural cover within shooting range of a tank with fresh sign is a reliable setup for hot-weather hunts.
