Canyonlands Natural History Association
Canyonlands Natural History Association (CNHA) is a nonprofit organization assisting the National Park Service in its educational, interpretive and scientific programs throughout southeast Utah. Known as a "cooperating association," CNHA’s goals include enhancing visitors' understanding and appreciation of public lands by providing a selection of quality, educational materials for sale in many vistor centers. Twenty percent of these sales is returned to the National Park Service and other federal land management agencies.
CNHA operates the bookstore at the Arches Visitor Center.
