Volcano or not, that is the question
Larry Chitwood, a geologist at Deschutes National Forest, told The Oregonian the pooling magma is under tremendous pressure causing the Earth's surface to expand and bulge. The uplift could be anything from the early stages of a volcano, to a pooling of liquid rock.
USGS geologists admit, they just don't know. In March 2004, 350 small earthquakes indicated magma was moving underground, but the bulge has been quiet since.
