One of the amazing wonders about Lake Tahoe is how crystal clear the water is. You can actually take a boat out on the lake and see all the rocks and pebbles up to 80 feet (possibly further down).
This picture is probably only shows a depth of 10 to 15 feet. However, the detail is absolutely amazing.
On a side not this picture was taken about 10 minutes away from from the famous Pondarosa Ranch. The very one that was featured by everybody's favorite western TV show "Bonanza."
