Unit S33

Several peaks anchor the unit for navigation and spotting: Anvil Mountain, Hurricane Peak, American Peak, and Macomber Peak serve as recognizable reference points across the high country. Spring Creek Pass and Stony Pass are critical saddles that bighorn use seasonally and hunters traverse for access. Key basins for reconnaissance include American Basin, Hurricane Basin, and Cataract Basin—these are prime glassing grounds.

Cooper Lake, Sloan Lake, and Lake San Cristobal offer visual orientation points at mid-elevation. The ridge systems around Dallas Divide and the high traverses between major basins create the actual hunting terrain. Iron Beds and other cliff features scattered through the unit provide escape habitat essential to sheep survival and hunting strategy.

This unit is pure high country. Terrain starts around 8,300 feet in the lower drainages and climbs steadily into true alpine country above 13,000 feet, with several summits exceeding 14,000 feet. The landscape transitions through scattered subalpine timber—Engelmann spruce and subalpine fir—interspersed with increasingly open terrain as elevation gains.

Above timberline, rocky alpine meadows and tundra dominate, carved into basins and saddles between steep peaks. These basins—Cataract, Schafer, Slagle, American, Hurricane—are the visual and functional heart of the unit, offering both sheep habitat and glassing vantage points. The steep flanks connecting basins provide escape terrain that defines bighorn country.

The unit benefits from good road access to its perimeter via U.S. 550 from the west, Colorado 149 from the northeast, and Colorado 110 from the south. Silverton and Lake City both have year-round access and amenities, making this a unit that can attract significant pressure during the September and November seasons. However, once off the roads, the steep terrain and high complexity thin out hunters quickly.

Most pressure concentrates in accessible basins and lower slopes near trailheads. The connected road network means hunters can stage from established infrastructure, but the actual sheep habitat requires scrambling through difficult, exposed terrain where physical fitness becomes the limiting factor. Early-season crowds near trails diminish substantially with elevation and distance from access points.

S33 encompasses the Lake Fork and Pole Mountain country straddling Hinsdale and San Juan counties in the central San Juan Mountains. The unit stretches from Colorado 149 on the east to U.S. 550 on the west, with the Gunnison-Hinsdale county line forming the northern boundary and the Rio Grande River defining much of the southern edge. This is rugged, high-elevation terrain in one of Colorado's most dramatic mountain ranges.

The geography funnels between established towns—Silverton to the south, Lake City to the north, and Henson/Middleton to the west—all serving as logical staging points for hunters accessing the alpine basins and ridge systems that characterize the unit.

Water is sparse at the elevations where bighorn concentrate, making specific knowledge of seeps and springs essential. Cooper Creek, Ruby Creek, and the South Fork Animas River drain major portions of the unit at lower elevations and support reliable flow. Higher up, seasonal snowmelt feeds small streams and seeps—these are ephemeral and unpredictable.

Cinnamon Creek, Big Buck Creek, and various unnamed drainages provide intermittent water during spring and early summer, but by late season, bighorn are forced to specific reliable sources. Hunters must scout water locations before the season; sheep movements often revolve around moisture availability. Reservoirs like Lake San Cristobal offer obvious water in lower basins but are not where active sheep hunting typically occurs.

Mountain bighorn in S33 occupy the high alpine basins and ridge systems above timberline and in scattered rocky breaks through the subalpine zone. Early season (September) finds sheep highest, in the true alpine basins where they feed on tundra vegetation and use cliff terrain for security. Glassing from passes and high saddles—Spring Creek, Stony, Cinnamon—is the primary scouting method; bighorn are visible at range across open terrain.

Hunters must locate water sources and intercept sheep during their movements between feeding and bedding areas, typically in early morning and evening. The steep terrain demands fit mountaineers; direct approaches often fail, requiring understanding of sheep escape routes and elevation advantages. By November, sheep may drop to slightly lower basins, but they remain in rocky, exposed country where spotting remains the key skill.

Success depends on fitness, patience with glassing, understanding of seasonal movement patterns, and ability to navigate complex, steep terrain safely.
