Red Rock Lakes National Wildlife Refuge and the Centennial Valley Professional Review and Guide
"Birding at Red Rock Lakes is spectacular. More than 50,000 ducks and geese may stage here during migration, and shorebirds are also found during this period. General Information: Red Rock Lakes, creek, and river are named after the red- colored rock outcrops near the town of Dell along Interstate 15. In 1935, Red Rock Lakes Migratory Bird Refuge was established, later renamed Red Rock Lakes National Wildlife Refuge. The Centennial Valley (and mountain range) was named in honor of the 100th anniversary of this country and coinciding with settlement by white men in this valley.
The 42,000-acre refuge contains a vast array of habitat, including high-elevation sage brush-grasslands, wet meadows and wetlands at 6,600 feet, cool aspen-coniferous and coniferous forests of the subalpine zone, and harsh alpine habitats on the high peaks of the Centennial Mountains. These diverse habitats give Red Rocks its unique character and provide food and cover for a correspondingly diverse range of wildlife."
