ABC WEDNESDAY LETTER " T "
Today is ABC Wednesday and we have arrived at the Letter " T ".
" T " is for Tufa Towers. I took this picture a few weeks ago when we visited the Mono Lake Tufa State Reserve, which is located in California.
This Reserve was established to preserve the calcium-carbonate spires and knobs formed by interaction of freshwater springs with the alkaline lake waters. The Lake is about 65 square miles and is considered over 1 million years old, one of the oldest lakes in North America. Mono Lake has no outlet. Salt and minerals washed into the lake from Eastern Sierra streams. The freshwater evaporated leaving salt and minerals behind so that the lake is now about 2 1/2 times as salty and 80 times as alkaline as the ocean.
What you see in this late afternoon photo are Tufas. They are essentially common limestone.
Tufa Towers grow exclusively underwater and some even grow to heights of more than 30 feet. As the Lake has evaporated the Tufa Towers have become visible and look almost like a moonscape.
In all my years of living in California I had never been to Mono Lake and its Tufa Towers. It is definitely a must see amazing creation of nature.
This picture looks best enlarged.
