Unit S16

Cimarrona Peak stands as the visual anchor of the unit and valuable glassing point. Knife Edge, Castle Rock, and Rooster Rock provide distinctive navigation references along the high ridges. The Red Lakes complex and Palisade Lakes offer reliable water sources and high-elevation base areas.

Major drainages—Trout Creek, Jumper Creek, and Cimarrona Creek—serve as natural travel corridors and navigation aids through the forested sections. Grizzly Pass and the trail network via Trail 539 provide traditional entry routes. These features collectively create a landscape readable for experienced backcountry travelers.

Entirely high-country terrain, S16 spans from about 7,600 feet in creek bottoms to nearly 13,000 feet at Cimarrona Peak, with the unit concentrated above 9,500 feet. Dense forest dominates lower and mid-elevations—spruce-fir and subalpine forest typical of Colorado's high San Juans. As elevation increases, the forest opens into scattered timber, windswept krummholz, and ultimately bare alpine tundra on exposed ridges and summits.

Broad meadows like Palisade and Elk Park interrupt the timber, providing critical sheep habitat and winter range. The terrain presents classic high-alpine sheep country with cliff bands, talus fields, and ridgeline escape terrain.

S16 connects to the outside via trail networks and approximately 248 miles of varying road quality, though density is low and no highways penetrate the unit. Access is concentrated through established trailheads requiring multi-day pack approaches. This remoteness limits overall pressure relative to lower, road-accessible units, but the high-country trails do see use.

Most hunters will access via Grizzly Pass or the Piedra River drainage. The terrain's complexity and elevation commitment mean only serious backcountry hunters typically pursue sheep here, creating pockets of solitude despite moderate accessibility.

S16 encompasses the Cimarrona Peak area of the San Juan Mountains, bounded by the Rio Grande River to the north and major drainages—Trout Creek, Piedra River, and Weminuche Creek—defining the eastern, southern, and western margins. The unit sits in the heart of rough alpine terrain straddling Hinsdale, Mineral, and Archuleta counties. This is remote, high-elevation country with limited road infrastructure and substantial public lands, making it a true backcountry proposition.

The terrain's character is defined by the sharp transition from forested slopes to exposed ridges and peaks that reach nearly 13,000 feet.

Water sources are scattered but present throughout S16's drainage system. Perennial streams including Trout Creek, Jumper Creek, and Cimarrona Creek flow through major valleys and can be relied upon. The lakes—Red Lakes, Palisade Lakes, Trout Lake, and Baldy Lake—provide concentrated water in alpine basins.

Numerous springs throughout the unit (Divide Park Springs, Notch Spring, Chub Spring, Turkey Park Spring) supplement creek water, though some are seasonal. Early-season hunters should plan water carries in high basin camps. The network of water sources is sufficient to sustain sheep populations across the unit.

S16 is dedicated sheep habitat across all its high-elevation terrain. Successful hunting demands aggressive ridge glassing and willingness to hunt from 10,000 feet and higher. Early season (August-September) concentrates sheep on high basins and ridges; access trails before snow.

Focus on the broad meadows (Palisade, Elk Park, Poison Park) where sheep feed and water in early season, and the exposed ridge systems where escape terrain and visibility favor glassing. The dense forest requires careful stalking through timber to reach open country. Plan for 3-5 day minimum pack trips.

Route-finding and weather exposure are the main challenges; physical fitness and navigation competence are essential.
