Mount Martin (Alaska)

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 Template:Convert higher than the surrounding ridge.<ref name="geomapkatmai1">Template:Cite journal</ref> 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.<ref name="avo1">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Mount Martin is relatively young, perched on a ridge and partly overlaying deposits from nearby Alagogshak volcanic edifice.<ref name="avo1"/>

The volcano is named for George C. Martin, who was the first person to visit the Valley of Ten Thousand Smokes after the 1912 eruption of Novarupta.
