Oregon Researchers Discover 580k-Year Climate Archive in Nevada

Kathleen Wendt led a team in Oregon State to find a calcite deposit in Devils Hole, Nevada.
The deposit preserves 580,000 years of climate history in arid regions.
Scientists used groundwater deposits to record climate data in the Southwest.
Wendt drilled a 1-meter core and analyzed oxygen isotopes for climate reconstruction.
Analysis shows alternating glacial and interglacial periods linked to Pacific storm shifts.
The study fills a terrestrial gap for understanding arid US Southwest climates.
