Galena Summit The Galena Lodge (in historic Galena) is at , on the Ketchum side of the summit, and hosts cross country skiing. Collegiate alpine ski races were held on the summit in late 1947, due to a lack of snow at Sun Valley, and supplies were dropped in by airplane. The Ore-Ida Women's Challenge bicycle race (1984–2002) had a stage that crested the summit. Galena is a mineral, lead sulfide, an important lead ore; deposits of galena often contain silver. Galena Summit Galena Summit is a high mountain pass in the western United States in central Idaho, at an elevation of
Ore genesis classified hydrothermal deposits as "hypothermal", "mesothermal", "epithermal", and "telethermal". Epithermal deposits are hydrothermal ore deposits formed at low temperatures (50-200 °C) near the Earth´s surface (<1500 m), that fill veins, breccias, and stockworks. The age of formation of epithermal deposits in México is currently being investigated. "As they require the conjunction of specific environmental conditions to form, particular mineral deposit types tend to occupy specific geodynamic niches," therefore, this page has been organised by metal commodity. It is also possible to organise theories the other way, namely according to geological criteria of formation. Often ores of the same metal can
