| | Battle of Oregon's bulge |
 | | The bulge, in the Three Sisters Wilderness Area -- named after three volcanic peaks -- was detected in March 2001 by a geologist using a new imaging technology called radar interferometry, which uses satellites to measure changes in Earth's surface. |
 | | The bulge -- or uplift, as geologists call it -- could grow into a cinder cone, which is a hill of volcanic fragments; become a shield volcano, which has a broad, gentle slope; or remain merely a bump, according to the USGS. |
 | | The slope of the bulge is so gradual, and the terrain so rich in other natural formations such as hills and ridges, that many people don't even know when they're standing on top of it. |
