Draper Natural History Museum Lunchtime Expedition

Geologist Gretchen Hurley presents From Ancient Rivers to Silent Cliffs: The Geomorphology of Golden Eagle Nesting and Hunting Habitats in the Bighorn Basin, Wyoming. Golden eagle nests are typically clustered along prominent sandstone cliff faces adjacent to large, open foraging areas. These cliffs also provide important habitat for other wildlife such as cottontails and other prey species. Hurley’s talk explores the geological nature of these sandstone cliffs as preferred by golden eagles for nesting habitat, hunting, and reconnaissance perches.

Lunchtime Expeditions are supported in part by Sage Creek Ranch and the Nancy-Carroll Draper Foundation.
