Mount Martin (Alaska)
Stratovolcano in the state of Alaska
Summary
Mount Martin is a stratovolcano, located on the Alaska Peninsula, United States, in Katmai National Park and Preserve. It is one of the volcanoes in the vicinity of the Valley of Ten Thousand Smokes. Mount Martin's cone stands only about 500 metres (1,600 ft) higher than the surrounding ridge. Although an eruption in 1953 is now considered questionable and no other confirmed eruptive activity has taken place at Mount Martin, there is intense fumarolic activity within its summit crater. The summit crater is also breached to the southeast. The 300 m (984 ft)-wide summit crater is often ice-free due to the geothermal heat and contains an intermittent acidic crater lake. The fumaroles in the summit crater produce extensive sulfur deposits.

Added map to info box.
Updated info box. Mount Martin is on the USGS Mount Katmai A-5 map and is located nowhere near Adak.
added [[Category:Holocene stratovolcanoes]] using [[WP:HC|HotCat]]
Edited info box. It is currently unknown when Mount Martin last erupted. The February 1953 eruption was at Trident Volcano. A seismic swarm occurred at Mount Martin in 2006, raising the alert level, but with no eruption. Vigorous fumaroles at the mountain are common per AVO.
