That wall of rock sources to an immense volcanic event at Yellowstone National Park at some point in its distant past. That wall is the side-on view of a thick layer of enamel over the land of the park from a massive volcanic flow. (Interrete: Ancient super-eruptions in Yellowstone Hotspot track ‘significantly larger’ than expected)

The entire cliff would have been deposited very quickly from a fast-moving current of hot gas and ash (a pyroclastic density current), and the extreme temperatures (900-1000°C) caused the ash to weld to the ground and effectively enameled the area in dense volcanic glass. Note how the ancient top soil has been baked to orange terracotta in response to the intense heat.

Can you even imagine the extraordinary force of the event, one which they believe may have happened half a dozen times. After Mount Saint Helens erupted, there was a layer of dust on the land and that was hugely destructive but now extrapolate that problem to this one and I doubt it's even possible to conceive of Mother Nature's fury in this situation. Whatever the reason, we did not cause it as this was long before the time of Man.
Sometimes there is talk of 'controlling Nature' in this way or that and, here at the Rockhouse, we see the only logical response to that is to raise one eyebrow and say, "Oh, really? That's such a precious idea, darlin'!"
