Rockfall A rockfall of gritstone rock tumbles toward the viewer. Change here happens by miniscule fractional shift, but those gradual steps add up. In several million years even these massive bodies of stone will be gone. The process of geologic formation and transformation is quite amazing. We have the privilege to see an intermediate step of that process.
