Where On Google Earth #218

After many fruitless attempts, I finally bagged a "Where on Google Earth," number 217, at Microecos. So in the spirit of keeping this game running smoothly and swiftly, here's number 218.

To win this and host the next WOGE, identify the latitude and longitude of this location, and describe a little of the geology here. I have no idea how difficult this will be, but I'm going to invoke the Schott rule: previous winners must wait one hour for each time they've won. Current time is 10:47 AM PDT, 5:47 PM UTC/GMT.
