Fossilized Footprints Reveal Human Habitation of North America Thousands of Years Earlier than Previously Thought

ALAMOGORDO – New scientific research conducted at White Sands National Park in New Mexico has uncovered the oldest known human footprints in North America. The discovery reveals evidence of human occupation in the Tularosa Basin beginning at least 23,000 years ago, thousands of years earlier than previously thought. 

USGS Science Centers in Region 7-Upper Colorado Basin conduct a large number of cooperative and collaborative projects with other agencies and partners. A sampling of those projects are shown below on this web page.

Data release for Oxygen isotopes in terrestrial gastropod shells track Quaternary climate change in the American Southwest

Recent studies have shown the oxygen isotopic composition (delta18O) of modern terrestrial gastropod shells is determined largely by the delta18O of precipitation. This implies that fossil shells could be used to reconstruct the delta18O of paleo-precipitation as long as the hydrologic pathways of the local watershed and the shell isotope systematics are well understood.
