Ah-Shi-Sle-Pah Wilderness Study Area
Ah-Shi-Sle-Pah Wilderness Study Area is located in San Juan County, New Mexico between Chaco Canyon and the De-Na-Zin Wilderness. The Wilderness Study Area (WSA) has multicolored badlands, sandstone hoodoos, petrified wood and dinosaur bones, similar to those found in the nearby Bisti Badlands and De-Na-Zin Wilderness.
The BLM Wilderness Study Area was declared in May 1992, and would protect an area of about 26.5 km2. (6,563 acres) The area was prospected by the renowned dinosaur hunter Charles Hazelius Sternberg in the summer of 1921. 〔(Ah-shi-sle-pah Wilderness Study Area ) by Isabel Synnatschke 〕 Sternberg collected the type specimen of ''Pentaceratops fenestratus'', a ceratopsid dinosaur from the late Cretaceous Period, within the WSA. Specimens from this area form a significant part of the vertebrate paleontology collection at the Museum of Evolution, University of Uppsala, Sweden.〔Sullivan, R.M. 2006. Ah-shi-sle-pah Wilderness Study Area (San Juan Basin, New Mexico): A paleontological (and historical) treasure and resource. New Mexico Museum of Natural History and Science Bulletin 34:169-174. (PDF )〕 Note that fossil collecting here without a permit is prohibited by law.
==Geology==
Rock units within the Ah-Shi-Sle-Pah WSA include most of the upper Fruitland Formation (Fossil Forest Member) and lower part of the Kirtland
Formation (Hunter Wash Member), both late Cretaceous in age. The rocks are dominated by mudstones and intermittent sandstones, with occasional resistant channel sandstones.〔
