1. Three Buttes Marker
East Butte (farthest east) flowed up and cooled quickly about 600,000 years ago, while Big Southern Butte (south of here) emerged about 300,000 years ago. Although East Butte and Middle Butte have a similar appearance, they were formed in differetn ways. A dome of melted rock called rhyolite that rose up through a volcanic fissure became East Butte. Middle Butte, however, is a block of hard lava (basalt) pushed up by volcanic activity from below.
