“. . . the water was not merely transparent, but dazzlingly, brilliantly so.”
- a description of Lake Tahoe by Mark Twain, Roughing It (1871)
And so it is today (purity in the high 90s), but it is in danger. To test the water clarity scientists lower a one foot white disk into the water. Years ago, this disc could be seen from the surface when it was at the 100 foot depth. Now it is not visible below 70 feet. The cause is the lake itself which draws so many to see its beauty or to live there. More people result in more pollutants. They are working to bring it back to its old purity.
This shot caused me to admire the water and the rocks beneath it. But it also made me wish I knew the story behind how those boulders came to be where they are and why some are stacked.
