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 prominent smoother-surfaced 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.
