Lassen Peak is a lava dome volcano. In fact, it is the world's biggest lava dome. However, Lassen Peak is not exactly your typical dome. Most lava domes don't have craters and don't erupt again after formation. However, Lassen Peak both has summit craters and erupted in the early 20th century LONG after its formation. In fact, the eruptions of the early 20th century were more typical of a stratovolcano than a dome.

∙ 15y agoRoughly 27,000 years ago, Lassen started to form as a mound-shaped dacite lava dome pushed its way through Tehama's destroyed north-eastern flank. As the lava dome pushed grow it shattered overlaying rock, which formed a blanket of angular talus around the emerging steep-sided volcano. It probably looked much like the nearby 1,100-year-old Chaos Crags
