Remember this interesting structure that I saw at the Saratoga Spa State Park on September 30th? Yesterday I received a comment from Nathan saying my “mystery photo is one of the more notable features along Geyser Creek known as Orenda Spring. The dome shaped structure you see is called a “tufa” which is basically a type of rock formed by the minerals in the spring water being deposited on the surface over time.” There’s more information about Tufas on Wikipedia here.
Thank you Nathan! I really appreciate it when people take their time to write to tell me things. This is an amazing rock formation!
How about everyone else, do you have any interesting rock formations in your area? I wish everyone a safe and happy New Year’s Eve!
