Dotsero is the most recent of four quaternary volcanic centers in NW Colorado. The locations and relative ages are: Dotsero (4,150 years ago), Willow Peak (undated), McCoy (0.64 Ma) and Triangle Peak (1.98 – 1.87 Ma). Triangle Peak was the only one of these not monogenetic as it produced at least 11 lava flows before activity stopped. Willow Peak is described as a young cinder cone with a narrow lava flow extending 6 – 7 km E.
