Molehill Mountain Detected From Space

SEWilco writes: "A four-inch mound was detected in Oregon recently near the Three Sisters volcanoes. Unlike a molehill, it's 10 miles across and was detected by radar from a satellite. The USGS Cascades Volcano Observatory compared two radar images which were taken four years apart and produced this image of the uplift. A USGS statement says the cause is uncertain, but a new pool of magma is suspected. There are no signs of pending eruptions."
