A 500-metre rock record drilled inside Bears Ears National Monument captures the last major icehouse-to-greenhouse climate transition, and may hold critical clues about geogenic toxins in a key regional hydrologic reservoir. Dr Jonathan Stine, University of Minnesota, is racing to find out before federal funding cuts end the work for good. In 1981, a drilling crew pulled ~500 metres of ancient rock from what is now Bears Ears National Monument in Utah.

The Fisher Valley basin (FVB), located adjacent to the Onion Creek salt diapir, Paradox basin, Utah, USA, constitutes one of the thickest collections of Quaternary sediments within the Colorado Plateau. These sediments are important for constraining regional paleoclimate environments as well as recent tectonic movement of the Onion Creek salt diapir.
