Geo 1095: May 25, Day 875: Collier Flow Berm

My camera's flash has a tendency to go off at times I think it's unnecessary, but it can lead to some interesting shots, such as this one. One has to clamber over the root system of this Doug fir to get at the rubbly hillside- the south edge of the Collier Cone Lava Flow- where you can see Anne and Chris in the upper left corner. It might be interesting to come up here with a couple bottles of food coloring to see if you can actually find the area(s) where the water is leaving the pool. It's shallow, and the volume is fairly small compared to the rate of flow from Upper Proxy Falls into it, so I'd bet the residence time of water in this pool is in the range of ten minutes or less.
