Day 12: Lake Kapowsin is shallow. Its maximum depth is roughly 30', and it is a veritable minefield of subsurface stumps due to the geologic process which formed it. When the Electron Mudflow surged down the Puyallup Valley approximately 500 years ago, it blocked the outlet to Ohop Creek and caused the water to back up in the basin we now know as the lake. The stumps are the remains of the drowned forest, and are a significant hazard for boaters, even one moving slower than usual in her kayak. One high spot of terrain remains as a 30-acre island on the northeast side. Most of the island is very brushy with salal and other shrubs, but a few open areas are considered "party spots" and are used occasionally as illegal campsites. A few pockets are so densely canopied that little light reaches the forest floor, a factor which led me to explore there for lichens and fungi. I found no unusual species, although there was a notable abundance of Evernia on the few Doug firs growing among the cedars.
