Things are heating up at Yellowstone National Park in two ways. Above normal temperatures above ground with the combination of underground heat from the parks super volcano, have combined to melt a road.

Firehole Lake Drive, a 3.3 mile looping road between Old Faithful and Lower Geyser Basin, melted and softened the pavement making it unsafe to drive on. The road will remain closed until it can be repaired. Right now it is described as asphalt soup; it turned a gravel road into oatmeal.  According to Dan Hottie, (how apropos is that name) because of underground heat and a shifting Earth, they see this type of thing quite a bit.
