Danger Cave

Danger Cave is a North American archaeological site located in the Bonneville Basin of western Utah around the Great Salt Lakes region, that features artifacts of the Desert Culture from c. 9000 BC until c. 500 AD. Through carbon-14 dating, it has been determined that there is very little evidence of human life in the Danger Cave area c. 11,000 BP, but there is much evidence of human life by 9000 BP.

Danger cave was first investigated in the 1930s by Elmer Smith, and excavated in the 1950s under the supervision of Jesse D. Jennings, professor at the University of Utah. Jennings' work at the site was considered ground-breaking due to his exacting standards in excavation and data analysis.
