Lemei Rock, seen from the Forlorn Lakes to the SE, forms the high point of the Indian Heaven volcanic field midway between Mount St. Helens and Mount Adams. The 600 km² field consists of overlapping small shield volcanoes with smaller cones and lava flows. The field was active from about 730,000 to about 9,000 years ago and contains some volcanic features that originated beneath a glacial icecap.
