Return to the field camp home page One of our major mapping projects is conducted near Pat O'Hara Mountain, Wyoming. Here we map Heart Mountain Thrust blocks, Tertiary volcanic rocks, and autuchthonous Paleozoic and Mesozoic sediments.
Students get to see evidence bearing on the classic Heart Mountain question.
The map area is between 7,000 and 8,000 feet in elevation. The field area is shown in the fore- to middle ground. We are typically there for wildflower season. We take time in the middle of camp for five days of field trip through some of the west's finest country and most interesting geology. Columnar jointed basalt , seen here north of Tower Falls, is one kind of volcanic rock we study on our field trip through Yellowstone.
