About the site

Wasden-Croft Archaeological Preserve is a series of three lava tube caves on private land formerly owned by Leonard Wasden and Kenneth Huskinson in the Arco Desert west of Idaho Falls. In the 1960s and '70s, archaeologists from the Upper Snake River Prehistoric Society and ISU uncovered thousands of years of flora, fauna, and evidence of Native American use, including some potentially significant findings still being studied. In 2018, Wasden's grandsons, Randy and Stephen Harris, donated the ~80,000 artifacts excavated thus far to MOI. Further scientific exploration remains to be done.

MOI is grateful to the Archaeological Conservancy, the owner of the preserve, for granting us access for educational purposes. The site is closed to the public.
