In 1971, wild horses and burros were found roaming across 53.8 million acres of Herd Areas (HAs), of which 42.4 million acres were under the BLM's jurisdiction. Today the BLM manages wild horses and burros in subsets of these HAs, known as Herd Management Areas (HMAs) that comprise 31.6 million acres, of which 26.9 million acres are under BLM management.
The Little Book Cliffs Wild HA consists of 36,113 acres of public lands characterized by gentle sloping plateau dissected by four major canyon systems (Main, Coal, Cottonwood and Spring Canyons) with many side canyons. Excellent opportunities exist for solitude and unconfined recreation. The outstanding scenic beauty, topographic diversity and the presence of the wild horse herd offers photography opportunities also. The ruggedness and abrupt slopes leading to the valley floor give it distinct character with many challenges for the visitor.
