Impact craters in the landscape and subsurface have received increasing attention in recent decades, particularly after popularization of the impact theory for the demise of the dinosaurs. Diluvialists also debate the possible role of impacts in the Genesis Flood. Thus, both uniformitarians and diluvialists have been on the lookout for more impact craters. In 2012, we investigated a candidate crater, Cayuse Basin in Judith Basin County, Montana. While we did not discover evidence for a crater, the process itself provided good lessons for both impact enthusiasts and detractors.
