These unusual limestone "tufa" rock formations form like the stalactites and stalagmites in caves, but these form underwater when calcium-laden spring water reaches the alkaline water of Mono Lake.
Ansel Adams talked a lot about visualizing the results you want well before you trigger the shutter. I anticipated this shot weeks in advance, then invited the Panoramio and Google+ communities to join me here on the G+/Panoramio Eastern Sierra Photowalk. Over 30 people RSVP'd, and we met in groups of 5 to 25 at various points on the anticipated shooting schedule, posted to the Eastern Sierra Nevada Workshops page on Google+. In the coming weeks participants will be showing their best results in a group here on Panoramio: http://www.panoramio.com/group/88116
