About Table Mountain
Table Mountain is a stratovolcano rising to 2,097 meters (6,880 feet) in United States's North America Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Table Mountain is located in United States, within the Basin and Range Volcanic Province of the broader North America Volcanic Regions. Situated at 40.56° N, 121.55° W in the Northern Hemisphere, the volcano lies within a temperate climate zone. At 2,097 meters above sea level, Table Mountain rises above the surrounding terrain into montane or subalpine conditions. The elevation creates distinct ecological zones along its flanks, from forested lower slopes to exposed rocky terrain near the summit. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
GVP Reference Summary
Table Mountain, an andesitic stratovolcano at the NW corner of Lassen National Park, is an andesitic stratovolcano active about 1-2 million years ago. Red Lake Mountain, immediately to the NW of Table Mountain, is the source of youthful-looking basaltic and andesitic lava flows of late-Pleistocene age (Clynne, in Wood and Kienle 1990; Miller 1989).

How high is Table Mountain?+
Table Mountain has a summit elevation of 2,097 meters (6,880 feet) above sea level. At 2,097 meters, it is comparable in height to many significant mountain peaks and stands well above the tree line.
What type of volcano is Table Mountain?+
Table Mountain is classified as a Stratovolcano. Stratovolcanoes (also called composite volcanoes) are steep, conical volcanoes built up by many layers of hardened lava, tephra, and volcanic ash. They are among the most common and dangerous types, known for explosive eruptions.
Where is Table Mountain located?+
Table Mountain is located in United States, in the North America Volcanic Regions. More specifically, it lies within the Basin and Range Volcanic Province. Its exact coordinates are 40.557° latitude, -121.550° longitude.
Is it safe to visit Table Mountain?+
Table Mountain can generally be visited, but as with any volcano, visitors should check local conditions and any advisory notices before traveling. United States may have specific regulations for accessing volcanic areas. Guided tours are often the safest and most informative way to experience a volcano.
