Mountains
US Mountains and Volcanoes Quiz
Mount Rainier, Denali, Kīlauea, Mount St. Helens and 25 more: find the great mountains and volcanoes of the United States on the map, or learn them first.
Every mountain is labelled. Tap or click one (or pick it from the list) to see its height and state, and for a volcano its last and best-known eruptions. Zoom in to see every name.

Sources and notes
Heights are in metres and feet. Volcano heights, types, last eruptions and eruptions are from the Smithsonian Institution’s Global Volcanism Program (GVP). Other mountains’ heights and first ascents are from official sources, each checked against at least one other; US summits use the US Geological Survey where it has a current figure. Where sources disagree, the mountain’s card says so.
VEI is the Volcanic Explosivity Index, from 0 (lava flowing out gently) to 8 (the largest known eruptions). Each step up means about ten times as much ash and rock thrown out. The VEIs are the GVP’s.
“Continuing” means the GVP listed the eruption as ongoing when we checked its records in September 2026.
Other names count: local names and old spellings (Chomolungma, Sagarmatha, Citlaltépetl, Mount McKinley, Mount Cook), and you can add or leave out “Mount”, “Mt” or “Volcano”.
Find on the map: we name a place, you click its marker (or, for a range, its area). Practice gives you three tries and highlights the right part of the map after two misses; Test gives you three tries without hints; Strict gives you one. After the last miss, the answer is shown and the next one comes up.
Where places are too close to tell apart at the zoom you are at (Everest and Lhotse, the Gasherbrums, the Cascades, the Big Island of Hawaiʻi), their markers step apart, with a thin line to the true summit. Zoom in and each marker moves back to its place.
The US map uses the same Albers projection as our other US maps, with Alaska and Hawaii in insets. Mount Saint Elias is on the Alaska–Yukon border.

About these 29 mountains and volcanoes
The Cascade volcanoes, from Mount Baker in Washington to Lassen Peak in California, with Mount St. Helens and the caldera of Crater Lake; Alaska’s giants, Denali and Mount Saint Elias, and its busiest volcanoes; the four great volcanoes of Hawaiʻi; and the high points people climb and drive up, from Mount Whitney and Pikes Peak to Mount Washington and Katahdin in the East.
The United States has about 160 volcanoes that the US Geological Survey counts as potentially active, most of them in Alaska. Kīlauea and Mauna Loa, on the Island of Hawaiʻi, are among the most active on Earth.

Heights are the cited sources’; where others disagree, the mountain’s card in the quiz says so.
