These white dead trees create an otherworldly scene around many of the geysers at Yellowstone. I am not sure why living trees are growing amongst them: are the dead trees silicified and preserved, to be joined by the living trees when they succumb to the harsh environment; or perhaps the conditions have changed allowing a new generation of trees to survive; or perhaps the dead trees were burned in one of the many forest fires that occurred at Yellowstone before being covered in the minerals expelled by the geysers.
