Phase Diagram of Water
Snake River Canyon, Targhee National Forest, Wyoming, 2014
The last time I looked, there were 16 different phases for water, 13 of which represent different solid-state forms. That's what I had in mind when I got nearly all the way down to the Snake River for this view of the river, the fast-moving transit of both liquid and solid water, the recrystallized newer snow layer, the harder ice beyond, the layered clouds above.
