Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
9,621-acre wilderness unit of Bitter Lake National Wildlife Refuge northeast of Roswell. Protects Chihuahuan Desert scrub, red-rock bluffs, Pecos River corridor segments, and sinkhole lakes that support native species including Pecos pupfish. Day-use foot and horse entry only—primitive wildlife viewing distinct from the refuge’s main wetland auto-tour unit.
