Historical photograph of Lassen Peak by Benjamin Loomis, May 22, 1915A second view of Lassen Peak and the Deveastated Area following an explosive eruption and mudflowk. The crater of the volcano is visible, revealing that a lava dome which had previously been growing there was destroyed by the explosion.
