Soda Dam, along the Jemez River, is a travertine dam formed across a gorge in Precambrian granite-gneiss SW of the rim of Valles caldera.  The travertine has been deposited over the past 5000 years by carbonated thermal waters discharged along the Jemez fault zone.  About 15 hot springs related to the Valles caldera thermal system are found at this location. Photo by Lee Siebert, 1989 (Smithsonian Institution).
