Place
Trinchera Ranch spans roughly 172,000 acres in Costilla County, Colorado, rising from the San Luis Valley floor at about 7,500 feet to the 14,345-foot summit of Blanca Peak. Elevation crosses four biogeoclimatic zones in a single property: high-altitude grassland, montane forest, subalpine, and alpine tundra.

Vegetation & ecosystems
Native high-altitude grassland under managed grazing; Sangre de Cristo montane forest of ponderosa pine, Douglas fir, and Engelmann spruce; subalpine and alpine communities above treeline on the fourteeners; and riparian and wetland corridors along the headwaters drainages. The Blanca Sawmill operates on the property for fire mitigation and forest health.
Water
The ranch sits in the Rio Grande headwaters basin — the San Luis Valley is where the river begins. Multiple tributary drainages originate on the property, and active restoration includes Rio Grande cutthroat trout habitat work and beaver-dam analog wetland engineering. Historical water rights require detailed decree review and are not characterized here.
