US Hwy 285 in the San Luis Valley crosses the Russell Lakes National Natural Landmark. Established in 1975 in Saguache County, the site protects Colorado’s largest remaining bulrush marsh and provides plant and animal habitat in the increasing developed mountain park. Looking east from the “visitor’s center”, you might be able to pick out Great Sand Dunes National Park and Preserve at the base of the Sangre de Cristos.
