This is pretty interesting about the tufa....
And here is the rock of the petrified springs...the tallest tufa in town! LOL
I could not resist taking this shot. This tufa is mighty bird-like don't you agree?
A swallow lifts its wings for take off. There were many zooming and swishing across the top of the lake and headed for their nests in the tufa...hmmm tufa lodges, tufa condos, tufa tenements! LOL
