The situation
What’s happening to Dinosaur
In its second-quarter 2026 Utah lease sale the BLM offered oil and gas leases on 39 parcels covering more than 54,000 acres near Arches National Park, Dinosaur National Monument and Moab. A coalition of conservation groups asked the BLM to defer every parcel; the BLM’s July 2026 decision offered all 39. The monument itself is a landscape of deep river canyons and some of the richest fossil beds in North America.
