Looking back down the path from Upper Proxy Falls (i.e., the falls are behind us in this view), The Collier Flow is on the right, and the southern edge of the valley is on the left. Has this notch been reworked by running water? It's not clear, but it seems possible. It would certainly fit with
the idea of burst floods contributing soil components (clastic sediment and plant debris) to the surface of the lava flow, and fostering an environment for rapid recolonization and reforestation. I have a few more photos of this notch, and I'll post at least one more, but looking over them, I see nothing convincing either way. Next time I get back here, I should see if I can spot
rounded gravel farther down the notch- it drops quickly just past that saddle.
