Lava Beds National Monument is a land with a tumultuous past, both geological and historical. Over the last half-million years, this high desert has experienced volcanic eruptions, creating a very rugged landscape of lava tubes, fumaroles, spatter cones, pit craters, volcanic fields and cinder cones. In 1872 and 1873, the Modoc War took place in this area pitting a band of natives led by Kintpuash (also known as Captain Jack) against the army of the United States. Gillem's Camp, named after Colonel Alvin C. Gillem, is where the army was headquartered during the Modoc War. Pictured here is the camp surrounded by rabbit brush (Ericameria nauseosa) in bloom. Gillem's Camp is located in Lava Beds National Monument, California, USA.
