Trident, seen here from Baked Mountain to its NW, was initially named for its three prominent summits. A series of eruptions from 1953 until 1968 constructed a fourth cone, which forms the smoother peak to the right. As many as 23 lava domes are found in the Trident volcanic complex. The 1912 Novarupta lava dome is visible to the lower center.
