The panorama above shows Panum Crater, a plug-dome volcano located just south of Mono Lake, California. It's part of the Mono-Inyo Craters chain. This particular volcano is the youngest in the chain, having been formed in an explosive eruption approximately 650 years ago. This photo was taken on the east side of the 1.5-mile (2.5 km) Rim Trail at the crest of the pumice ejecta ring, which completely encircles the volcanic plug. A shorter trail leads up into the plug itself for close examination of rhyolitic blocks, spires, and obsidian (volcanic glass). The snow-capped mountains in the background are the Tioga Pass area of the Sierra Nevada range. Photo taken on May 3, 2015.
