News from the Field: Day 13--Geothermal Plant and Bodie

Today the group explored two aspects of exploitation of resources in the Eastern Sierra: a morning tour of the Casa Diablo geothermal power plant, followed by an afternoon at Bodie, a preserved mining town from the late 19th century. Our tour guide was Rod, a prospector, and 7-year veteran ranger at Bodie State Park, who shared his knowledge of the natural history of the Bodie Hills, the story of gold mining in the Sierra Nevada, and the unusual society that inhabited this mining village. We returned to SNARL for our last evening--cleanup, cards, and starlight strolls. Off for our last day in the Sierra tomorrow--a hike up Lundy Canyon and a closing barbeque.

We start the day with a tour of the Casa Diablo geothermal power plant, which uses superheated steam from the Long Valley magma body to generate 45 Megawatts of electricity. 
Jim Shallcross, an operator for the plant, explains the geothermal technology. And check out that cool license plate!
The group looks on as Jim explains the background on geothermal development at Casa Diablo. A fumarole (steam vent) is visible in the background. 
On a beautiful morning, Jim leads the group through the geothermal area.

Before we leave the site, the group can't resist posing in front of another hazard sign!

Outside the stamp mill, Jack and Daniel rest by a piece of high-grade gold ore, and the 'widow-maker' pneumatic drill.
Inside the stamp mill, Rod shows off the machine room.

John chats with Adam and Jack by an old Bodie wagon.  Do you think we could trade this for our old Chevy Venture minivan?
