Science of Water


Dr. Kate Zeigler is a geologist/hydrologist who works with farmers and ranchers in New Mexico and Colorado to provide scientific data about their wells and water table. Kate  is the owner of Zeigler Geologic Consulting, LLC, a small woman-owned business based in Albuquerque. Born in Montana and raised in Texas, she came to New Mexico in 1999 for graduate school. She earned her Bachelors from Rice University in Geology and Anthropology and obtained her M.S. and Ph.D. from the University of New Mexico. Her master’s thesis focused on a large fossil bonebed near Ghost Ranch, New Mexico and her doctoral research included developing one of the first complete magnetic polarity chronologies for Triassic age rocks in New Mexico. After graduating, Kate went on to become a consulting geologist and found her calling in working with rural agricultural communities to develop groundwater resource datasets. We talk about the importance of not only data collection but also building trust and community decision-making for future sustainability on arid agricultural lands.

Episode 72 – Bringing Buffalo back home

The Eastern Shoshone people traditionally survived with the buffalo, and their way of life suffered when tens of millions of buffalo were killed by the US government. But now they’re returning to the land–and starting to renew a culture.
