““Light. Space. Light and space without time, I think, for this is a country with only the slightest traces of human history. In the doctrine of the geologists with their scheme of ages, eons and epochs all is flux, as Heraclitus taught, but from the mortally human point of view the landscape of the Colorado is like a section of eternity- timeless. In all my years in the canyon country I have yet see a rock fall, of its own volition, so to speak, aside from floods. To convince myself of the reality of change and therefore time I will sometimes push a stone over the edge of a cliff and watch it descend and wait- lighting my pipe- for the report of its impact and disintegration to return. Doing my bit to help, of course, aiding natural processes and verifying the hypotheses of geological morphology. But am not entirely convinced.””
