Unit 133

Several distinctive features provide reliable navigation anchors. Flattop Butte, Cone Mountain, and Brushy Knob serve as prominent summit references visible across the unit for orientation and glassing platforms. Saliba Mesa and The Hogback create north-south ridge systems useful for travel corridors and elk movement routes.

The series of canyons—Box, Miners, South, Hickok, and Apishapa—cut through the terrain as natural drainages and water-finding features. Merrit Spring, Big Dripping Spring, and Box Canyon Spring offer reliable water sources for staging camps or midday access points.

The unit occupies mid-elevation foothills spanning roughly 4,800 to 6,600 feet, creating a zone where grassland dominates lower elevations and sparse pinyon-juniper woodland becomes increasingly common as elevation rises. The higher ridges and mesa tops support scattered conifer cover interspersed with wide open benches and grassland parks. This openness distinguishes 133 from more heavily forested units to the west—the country feels more like rolling prairie with evergreen accent than true mountain forest.

Sagebrush and bitterbrush scrubland fills mid-elevation slopes, creating good transition habitat. The sparse timber means significant glassing country throughout.

Fair road access means ranch roads and county routes distribute across the unit fairly evenly, but the sparse public land percentage concentrates public-access opportunities. Most private land restricts direct hunting pressure. The I-25 proximity makes this weekend-accessible terrain that sees moderate pressure during rifle season.

Early mornings and midweek hunting encounter fewer people. The northern sections near Highway 10 see more traffic than southern reaches near the Apishapa. Accessibility paradoxically works both ways—easy access brings more hunters, but vast private acreage keeps the public pressure manageable compared to truly open units.

Unit 133 occupies the foothill zone of Huerfano, Pueblo, and Las Animas Counties, bracketed by Interstate 25 to the west and Colorado Highway 10 to the north. The Apishapa River forms the southern boundary, while the Colorado Interstate Gas Pipeline Road marks the eastern edge. This arrangement positions the unit as a buffer zone between the high country to the west and the plains to the east.

The geography creates a natural transition landscape where mountain and prairie ecology overlap. Access from Pueblo and Trinidad corridors is straightforward via I-25 frontage.

Perennial water is limited—the unit relies primarily on livestock reservoirs (Poma, Farr, Gabriel, Lambert, and others) and scattered springs rather than flowing streams. Salado Creek and Santa Clara Creek carry seasonal water after runoff but dry considerably in summer and fall. The canyon systems including Box, South, and Apishapa drainages provide the most reliable water corridors and serve as natural travel routes.

Hunters planning multiday efforts should plan camps near reservoir clusters or spring complexes rather than expecting year-round creek access. Early season offers better water availability; late season requires deliberate water strategy.

Elk in 133 concentrate in canyon systems and the higher ridge country where timber provides cover, particularly around Box Canyon, South Canyon, and along The Hogback system. They migrate between summer high country to the west and lower elevation grass in fall, using the canyons as travel corridors. Mule deer thrive throughout the transition zones where grassland meets pinyon-juniper, especially on benches and mesa edges providing both browse and visibility.

White-tailed deer favor the denser canyon bottoms and creek drainages. Pronghorn occupy the open grassland parks and broad benches year-round. Moose are present but rare.

Mountain lion hunting follows mule deer concentration areas. Plan early-season efforts in higher canyons; pivot to lower grassland approaches as temperatures drop and animals redistribute lower.
