While having lunch at the Whoa Nellie Deli, I noticed what I thought were whitecaps on Mono Lake. As the wind was blowing heartedly, I assumed it had stirred up waves. Yet as I kept watching, the white lines did not appear to be moving. After lunch, we headed to the Mono Lake Visitor Center to inquire about the phenomena. Apparently, on windy days when conditions are right, a constant wind can create stripes of alkaline foam in the water.
