Soda Dam Hot Springs, Sandoval County, is a cluster of fifteen hot springs whose mineral deposits have built a travertine dam across the Jemez River. The water is hot, well above a comfortable soak. Jemez Pueblo is about thirteen miles away. Who manages it and who may enter are both unrecorded, and the record gives no land unit. There is a photo, and the formation itself is the reason most people know the name.

Location

A short walk from a road, a few hundred feet; the road is nameless on the record. Elevation is moderately high, in snowy Jemez country with a middling yearly precipitation and cool average temperatures. Jemez Falls Campground lies under five miles off. The entry leaves out who manages the ground and any fee.

Hot water. Test it before trusting any pool. The best-time note says winter, and the snow here is real, so plan for it if you take that note literally. Water chemistry on record stops at pH and chloride, sampled in 1975. No fee is recorded. Camp at Jemez Falls if you want to stay nearby. Access is not stated, so check locally.

History of Soda Dam Hot Springs

Wikipedia describes the Soda Dam as a grouping of fifteen hot springs whose calcium carbonate and travertine deposits have formed a bridge over the Jemez River. It is also called the Jemez Springs Soda Dam, or Soda Dam for short.

Heat Below
126 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 77% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
