(The Salt Lake Tribune | Brian Maffly) In this March 27, 2018 photo, a crew erects a reworking rid on an old oil well on Alkali Ridge east of Blanding where the Bureau of Land Management has issued numerous new leases in an area blanketed with Anasazi artifacts. Obscure companies with no track record in the energy business are amassing leases here over the objections of historic preservation groups that fear BLM lacks sufficient information about thousands of cultural sites to ensure their protection should the area get drilled. The Southern Utah Wilderness Alliance filed a lawsuit on April 19, 2019, against BLM and others over the lease sales.
