Unit Fillmore B
High-desert basin country spanning sagebrush flats to scattered timber ridges across central Utah.
Hunter's Brief
Fillmore B covers diverse terrain from low sagebrush valleys to moderate-elevation ridges, anchored around the Pahvant Range and multiple reservoirs. Access is straightforward via connected road networks connecting Salina, Fillmore, and surrounding communities. Water availability from reservoirs and springs makes this country huntable, though distribution is limited in some areas. The terrain complexity rewards knowing the landscape—elevation changes and scattered timber create pockets of solitude despite reasonable road access.

Terrain Deep Dive
Landmarks & Navigation
Twin Peaks and the Pahvant Range dominate the eastern terrain, providing natural anchors for navigation and glassing opportunities. Clear Spot Flats and nearby reservoirs serve as logical reference points for orientation. Devils Kitchen Reservoir and Chokecherry Reservoir mark reliable water concentrations.
Key ridges including Blue Ridge, Sand Rock Ridge, and Mahogany Ridge break up the terrain and offer vantage points. Cove Fort Dog Valley Pass and The Narrows provide natural travel corridors through the country. Sulphur Creek and Fish Creek drainages offer established routes into the larger valleys, while the lava beds near The Cinders add distinctive volcanic features to the landscape.
Elevation & Habitat
The unit rises from lower sagebrush basins around 4,500 feet to scattered timber ridges near 10,000 feet, creating distinct habitat zones. Lower Pahvant Valley supports low-elevation desert shrub and grassland habitat typical of Great Basin terrain. Mid-elevation benches transition into ponderosa and juniper woodland scattered across ridges like the Pahvant Range and surrounding summits.
Upper reaches support conifer stands and aspen patches, though forest cover remains moderate overall. Vegetation patterns reflect the transition zone between basin floor and mountain terrain, with water-dependent riparian areas concentrated along creek bottoms and around reservoirs.
Access & Pressure
Over 2,600 miles of roads connect this vast unit, creating a well-networked landscape that supports access from multiple communities. I-15 and US-50 provide major through-routes, with secondary roads branching into valleys and toward ridges. Established towns including Fillmore, Scipio, Salina, and Ephraim serve as staging areas with services and supplies.
Road density supports fair vehicle access to basin areas, though ridgeline country requires more work. The terrain complexity rating of 7.7 suggests pressure concentrates on accessible valleys and reservoirs; hunters willing to work steeper terrain and ridges can find quieter country. Early season typically sees heavier use near water sources; late season may push hunters higher.
Boundaries & Context
Fillmore B spans across Juab, Millard, and Sevier counties in central Utah's Great Basin country. Boundaries run from SR-132 near Leamington west through Nephi, then south to I-70 and east to US-89 near Salina, encompassing the Pahvant Valley region and surrounding benches. The unit includes established communities like Fillmore, Scipio, and Aurora, with I-15 and US-50 providing major access corridors.
Multiple reservoirs and agricultural ditches indicate developed water infrastructure across historically productive ranching country. The unit excludes Native American trust lands and CWMUs per state management directives.
Water & Drainages
Water availability defines hunting success in Fillmore B. Sulphur Creek, Fish Creek, Corn Creek, and Meadow Creek provide perennial or seasonal flow, with Sulphur Creek being the most reliable drainage. Multiple reservoirs including Devils Kitchen, Clear Spot, Chokecherry, and Three Creeks offer reliable water sources for both wildlife and hunters. Springs scattered throughout—Twin Peaks Spring, Black Spring, Mud Springs, Cold Spring—support wildlife in otherwise drier areas.
Agricultural infrastructure including Lowline Canal and Current Spring Ditch indicates developed water management. Lower country can be water-scarce; hunting strategy should plan around known reservoirs and spring locations rather than assuming consistent creek flow.
Hunting Strategy
Fillmore B supports elk, mule deer, pronghorn, moose, mountain goat, desert bighorn sheep, and mountain lion, with habitat for each across elevation bands. Elk occupy mid to upper elevation timber around Twin Peaks and the Pahvant Range, especially in aspen and conifer stands; rut hunting focuses on ridges and benches. Mule deer span the entire unit—bucks pattern around juniper-sagebrush edges and creek bottoms during early season, migrating higher as temperatures rise.
Pronghorn inhabit open flats and basins where visibility favors optics-based hunting. Moose occupy riparian areas and wet drainages, particularly Fish Creek and Sulphur Creek bottoms. Mountain goat and desert bighorn require technical terrain at upper elevations and volcanic ridges.
Water sources become critical in late season; positioning near reservoirs and reliable springs concentrates scouting efforts.
