COVER: A 17.0 Ma lava flow of the Picture Gorge Basalt capping the 32 Ma tuff of Dale of the Tower Mountain volcanic field. The Picture Gorge Basalt is part of the main eruptive phase of flood basalt lavas of the Columbia River Basalt Group. The outcrop is spectacularly exposed along the North Fork of the John Day River, northeast Oregon, USA. See Cahoon et al., “Reshuffling the Columbia River Basalt chronology—Picture Gorge Basalt, the earliest- and longest-erupting formation,” p. 348–352.
