This SWA provides a break from the flat dry San Luis Valley floor. It is an as oasis of riparian woodland and ponds, mixed with some excellent sage habitat and small cattail marshes. Though closed during the summer waterfowl nesting season, this is still an excellent place to visit during fall migration; keep an eye out for passerine migrants in the cottonwoods, Marsh Wren and rails in the marsh, various duck species in the ponds, and Sage Sparrows in the sage along the entrance road. During the winter, sparrows and Northern Shrike are possible. Deer, rabbits and ground squirrels can be abundant, and muskrats and beaver swim in the ponds.
