WELCOME to the NEW VERSION of the Idaho EPSCoR "Biocomplexity in Extreme Environments" webpage!



Lying at the base of Steens Mountain, along the western edge of the Alvord Desert, are the Alvord Hot Springs. These springs are linearly aligned along approximately 120 meters of the Alvord fault. Temperatures range from about 60° to 80°C (averaging ~75°C). At least 45 cooler springs lie south of Alvord Hot Springs along the Alvord fault (see maps to the right).

To learn more about the datasets collected from Alvord Hot Springs, go to the Data Resources page. Terrestrial laser scanning has been done along the Alvord fault at Alvord Point (located in the southern portion of the maps below) in order to determine rates of deformation.
