About this map

Great Sand Dunes National Park and the Baca National Wildlife Refuge dominate this high-desert landscape in Alamosa County. The map details a complex hydrological network where seasonal and permanent waters like San Luis Lake and Head Lake collect in the basin. These waters are fed by a series of intermittent streams descending from the dunes, including Big Spring Cr, Little Spring Cr, and Arena Cr. The drainage patterns here are distinctive, as many streams terminate or pool in the sandy terrain rather than reaching a major river system. Local access is marked by the San Luis Lakes Swa Trl and a grid of rural lanes like Guffey Ln and Fifth Ave, illustrating the intersection of protected federal lands and localized agricultural or residential footprints in the San Luis Valley.
