I read Brendon Bosworth's article on Fallen Leaf Lake with great interest ("The forest at the bottom of the lake," HCN, 12/24/12). With my dive partner, John Foster, a retired California state archaeologist, I sampled sunken trees from nearby Tahoe and Donner Lake, mainly in the 1980s. In South Lake Tahoe, 16 rooted snags in ancient underwater forests indicated a mid-Holocene drying trend for a period of at least 1,300 years. A rather sobering thought: When will it happen again?
