The lake is highly alkaline, and subsurface springs (you can see them along the shoreline) feed the lake high amounts of dissolved calcium. The results are the tufa formations, which have been exposed as lake levels dropped. I only spent an evening and the following morning at Mono Lake and was fortunate to experience great light at both.
