Chilly Slough Wetland

The Chilly Slough (Thousand Springs) Wetland Conservation Area is one of the few remaining examples of a natural, high desert, spring-fed wetland. It sits at the base of Mount Borah and abounds with many species of wildlife throughout the year. A birdwatcher's paradise comes alive during the spring and autumn migrations, or when many species of birds choose the slough for the nesting season. The wetlands provide habitat for as many as 134 different birds, 27 mammals, 6 reptiles, 3 amphibians and 3 fish species. Birds include sandhill cranes, golden eagles, northern harrier, trumpeter swans, and many ducks, songbirds and shorebirds. Mammals include coyotes, muskrats, big brown bats, and wintering pronghorn antelope and mule deer. Fishes include brook and rainbow trout. A half-mile nature trail enables visitors to see the diversity of life found in the marsh up close.
