Hydrogeology of Silver Creek Field Trip, Western Harney Basin
Led by Hank Johnson & Dr. Steve Gingerich
Saturday & Sunday June 24-25, 9:30 am - 5:30 pm
Please join hydrogeologists Hank Johnson and Dr. Steve Gingerich for a two day field trip exploring the hydrogeology of Silver Creek in western Harney County. The first day we will make a series of stops to understand the recharge area of the aquifer system and the second day will focus on the discharge area.
This trip will follow Silver Creek from its headwaters in the Ponderosa forests of the Blue Mountains to its final destination in the wetlands and playas of the Malheur National Wildlife Refuge west of Harney Lake. Springs bookend the field trip, beginning with small-volume springs that feed upper Silver Creek and ending with large-volume thermal springs in Warm Springs Valley. The creek follows the Brothers Fault Zone for much of course as it flows across three major physiographic provinces: the Blue Mountains, the High Lava Plains, and the Basin and Range. We will explore how the complex geologic history of western Harney County has influenced the distribution of groundwater and surface water in the basin. And, how that distribution has influenced water resource management and development over the last 150 years.
