Arizona Unit 15B Bighorn Sheep Hunting Guide
Unit 15B sits in the low desert country of northwest Arizona, ranging from just over 1,000 feet up to roughly 5,455 feet in elevation across 186,573 acres. For hunters chasing desert bighorn sheep, this unit represents one of the most sought-after and difficult-to-draw tags in the state — a true once-in-a-lifetime pursuit that draws applicants who have waited a decade or more for a shot at a coveted permit. This article breaks down what the data shows about Unit 15B, what hunters can realistically expect, and how the application process works.
Desert bighorn hunting in Arizona is fundamentally different from most other big game pursuits in the state. There's no general season, no over-the-counter option, and no shortcut. Every single hunt in Unit 15B is a limited-quota draw tag, and the entire unit sits on 100% public land, giving drawn hunters full access to hunt the terrain without navigating private land permissions. That's a meaningful advantage for a species that requires extensive glassing and slow, deliberate stalking across open desert terrain.
HuntPilot Analysis: Is Unit 15B Worth Applying For?
For desert bighorn sheep specifically, the honest answer is yes — with the caveat that this is a long-term investment, not a quick-draw opportunity. The counties overlapping Unit 15B carry a strong history of trophy-class record-book entries, which signals that this landscape has consistently produced mature rams over multiple decades. That trophy pedigree, combined with 100% public land access and zero wilderness restrictions complicating access, makes this a unit worth having in an application strategy for any hunter serious about eventually punting a desert sheep tag.
That said, hunters need to go in with clear eyes about scale. The tag quota data shows this is an extremely limited-quota operation — hunt type 6008 moved from 1 tag in 2023 to 2 tags in 2025, and hunt type 6009 shifted from 2 tags in 2023 down to 1 in 2024 before returning to 2 tags in 2025. These are not typos. Desert bighorn permits statewide are issued in the single digits per unit, and Unit 15B is no exception. When only 1-2 tags exist for an entire hunt type, the entire hunter experience in a given year can be defined by a handful of individuals.
The harvest numbers reflect that same reality, and hunters should read them carefully rather than at face value. In 2025, 4 hunters harvested 4 animals for a 100% success rate — a strong showing consistent with how desert sheep hunts typically play out once a tag is drawn: hunters who draw a coveted sheep tag tend to prepare extensively, hire experienced guides or scouts, and dedicate the entire season to filling that one tag. In 2023, all 3 hunters were also successful. 2024 saw 3 hunters with 2 harvested, a 67% success rate. The clear pattern across these three years is that desert bighorn hunters in Unit 15B who draw a tag overwhelmingly fill it — success rates near or at 100% are the norm, not the exception, for this species once a permit is in hand.
The 2022 figure of 15 hunters and 200 harvested (a reported 1333% success rate) is a clear data anomaly, almost certainly reflecting a reporting or aggregation issue rather than an actual harvest event. Hunters should disregard that figure as representative of typical unit performance and instead rely on the 2023-2025 trend, which consistently shows small hunter numbers and high fill rates.
Trophy Quality
Desert bighorn sheep hunting in Unit 15B benefits from a genuinely strong trophy history. The counties overlapping this unit have produced a meaningful volume of record-book entries over time, which is a strong qualitative indicator for hunters wondering whether this unit can produce a mature, heavily-broomed ram worthy of a wall mount. It's worth noting, as is standard with all record-book data, that these entries are logged at the county level rather than being unit-exclusive — meaning the same historical records are shared across Unit 15B and any neighboring units that fall within those same counties. Rams counted in the record book may have been taken anywhere within that broader boundary, not necessarily inside Unit 15B specifically.
Still, a strong county-level trophy history is a meaningful signal. Desert bighorn habitat doesn't change dramatically at unit boundary lines, and a county with sustained trophy production generally reflects a healthy, mature ram population across the broader landscape, including Unit 15B. Hunters who draw a tag here should feel confident that the herd has the genetics and age structure to produce an exceptional ram, provided they put in the scouting time to locate one of the older, more reclusive animals that tend to hold the best headgear.
Access & Terrain
Unit 15B offers a wide elevation band, running from roughly 1,081 feet up near the low desert floor to 5,455 feet at its highest points. That spread means hunters can expect classic low desert bighorn habitat — rocky, broken terrain, steep canyon walls, and sparse vegetation that rewards long-range glassing over foot-pounding pursuit. Desert sheep in this kind of country typically bed on steep, rocky slopes where they can see approaching danger from a distance, so successful hunters spend the majority of their time behind spotting scopes rather than covering ground.
The standout access statistic for this unit is the public land figure: 100%. Every acre of Unit 15B's 186,573 total acres is public land, meaning hunters who draw a tag here won't need to negotiate private property access, request landowner permission, or work around fenced parcels that block travel corridors. This is about as favorable an access situation as a hunter can find in Arizona big game hunting, and it removes one of the biggest logistical headaches that plagues hunters in mixed-ownership units elsewhere in the state.
There is no wilderness designation recorded for this unit, meaning hunters won't face additional travel restrictions tied to wilderness area rules. Vehicle access to staging points and glassing knobs should be more straightforward than in units with heavy wilderness acreage, though hunters should still expect to do plenty of hiking once they're within range of a ram, since desert bighorn habitat is inherently rugged regardless of wilderness status.
Given the low elevation range and desert setting, hunters should prepare for hot, exposed conditions and limited water sources — both standard considerations for any desert bighorn hunt in this part of Arizona. Scouting trips should focus on identifying water sources, since desert bighorn activity concentrates heavily around these areas, particularly as temperatures rise.
How to Apply
Arizona's desert bighorn sheep hunts are exclusively limited-quota draw tags — there is no general season or over-the-counter option for this species anywhere in the state, and Unit 15B is no exception. Every hunter pursuing a ram here must first draw a tag through Arizona Game and Fish's controlled hunt permit application process.
Both resident and nonresident hunters apply through the same draw system, though tag allocations are split between resident and nonresident pools. Arizona's bonus point system rewards hunters who apply consistently over multiple years, and because desert bighorn tags are so limited — as few as 1 to 2 tags per hunt type in Unit 15B based on recent quota data — this is widely considered one of the most competitive draws in the state. Hunters serious about eventually drawing a tag here should expect this to be a multi-year, and often multi-decade, point-building strategy rather than a hunt they can plan for in the near term.
Because application deadlines, fees, and current bonus point requirements change with each draw cycle, hunters should not rely on static figures.

Frequently Asked Questions
What is the terrain like in Unit 15B? Unit 15B spans a wide elevation range from about 1,081 feet to 5,455 feet, characteristic of low desert bighorn sheep country — rocky, broken canyon terrain with sparse vegetation. This type of landscape favors long-distance glassing and patient stalking rather than fast-paced pursuit, and hunters should expect steep, rugged footing once they close the distance on a spotted ram.
What is harvest success like in Unit 15B? Based on 2023-2025 data, harvest success for desert bighorn sheep in Unit 15B has been consistently high, with 100% success rates in both 2023 and 2025, and a 67% success rate in 2024. These figures reflect the nature of desert sheep hunting broadly — hunters who draw one of the extremely limited tags typically dedicate significant time, resources, and often professional guiding to filling that tag, resulting in high overall fill rates once a permit is secured.
How big are the bighorn sheep in Unit 15B? The counties overlapping Unit 15B carry a strong history of producing trophy-class record-book rams, which indicates the broader landscape has the age structure and genetics to grow mature, well-developed rams. Because record-book entries are logged at the county level and shared with neighboring units, this data speaks to the region's trophy potential generally rather than confirming animals taken exclusively within Unit 15B's boundaries. Still, it's a strong qualitative sign for hunters hoping to find an exceptional ram.
Is Unit 15B worth applying for? Yes, for hunters committed to a long-term application strategy. The combination of 100% public land access, a strong regional trophy history, and consistently high harvest success rates once a tag is drawn make this a desirable unit for desert bighorn sheep. The tradeoff is extremely limited tag numbers — recent quota data shows as few as 1 to 2 tags per hunt type — meaning this is a patience game best suited to hunters willing to accumulate points over many years.
How many tags are issued in Unit 15B for desert bighorn sheep? Recent quota data shows hunt type 6008 increasing from 1 tag in 2023 to 2 tags in 2025, while hunt type 6009 has fluctuated between 1 and 2 tags across 2023-2025. These are among the smallest tag allocations of any big game hunt in Arizona, underscoring just how selective the draw process is for this unit. Hunters should check HuntPilot's Arizona unit page for the most current quota figures before applying.
