Photographer's Note

work has taken 130% of my time, which means I have not been here on TE as much as I'd like to, and I feel a little rusted when I longingly look at the camera bag. and the Opalescent Pool in Yellowstone National park's Black Sand Basin also looks a little rusted.

the Opalescent Pool has a cooler temperature than other thermal features at Black Sand Basin, just +62C (144F). early in its history Opalescent Pool was a boiling spring, surrounded by smaller springs, but by early 1950s it had turned into small dry pool. then the run-off from neighbouring Spouter Geyser flowed into it, and the increased water flow flooded the surrounding area, killing the trees. since then silica, a non-crystalline compound, has precipitated upon the dead tree trunks, slowly impregnates the wood and over time, with the absence of oxygen, eventually petrifies the wood.
