USGS survey analyzes earthquake hazards, geothermal resources

A survey conducted by the U.S. Geological Survey is assessing fault lines and possible geothermal resources on the Umatilla Indian Reservation.

Basalt cliffs run up the hillside along Thorn Hollow Road overlooking the Umatilla River, where Jonathan Glen and Brent Ritzinger with the U.S. Geological Survey arrived in a white Chevy Suburban.

The scientists parked on a gravel pullout and took stock of the red, rocky outcrops, debating the best places to drill for samples that could provide clues about what lies deep beneath the Earth’s surface.
