Soda Dam Hot Spring 2


The Soda Dam, along NM state road 4, is a large hot spring deposit, made mostly of calcium carbonate. The springs used to empty out onto the dam over the Jemez River, but most of the water now exits from the roadcut across the road. This page focuses on the microbial mats of the springs. See also the web page on Soda Dam Microbiology.
