When it was discovered that the rocky road was not a road but a natural arch, it was a reminder that our roads are built on bedrock, not the soil of a mountain, said Robert A. Boles, a professor of engineering at Texas A&M University.
And it reminded me of a scene from the movie “Tombstone,” in which the protagonist, the sheriff, is standing in front of a boulder, which is in fact a wall, but which looks as though it’s being climbed by a giant.
The boulder is the result of erosion that occurred as the rock layers fell over the past 4.6 billion years.
We call that erosion the “climbing process.”
As a result, it looks like the rock is actually being pushed over by the mountain.
The other part of the scene is the sheriff standing on top of a cliff face, facing the mountain and a view of the town below.
When we find out that we can’t walk on the rocky roads, the feeling is that we’re really being pushed off the cliff face by a natural force, said Boles.
“So that’s what we’ve got to do: we have to be willing to take on the challenge of climbing over rocks and find a way to get out of that situation.”
