Soda Dam, NM (# 0943)

Soda Dam, on NM-4. The ‘dam’ is a naturally occurring deposit, mostly of calcium carbonate from a spring at the site. The dam, 300 feet long and 50 feet high, continues to build – one of the many spots of flow from the spring is in about the center of the picture. To get a sense of the size of the dam, note the people in the river in the lower right side of the picture.
