There is a post over at Creation-Evolution Headlines that is interesting as it pertains to two things:
1. The Unreliability of Scientific Realism and
2. The Age of the Earth (namely the downfall of Uniformitarianism in favor of a return to Catastrophism).
The scientist who proposed this theory on the formation of canyons by catastrophic flooding did not make any connection to a global Flood and was probably a secular scientist and not a creationist. Nevertheless, the foundations of Uniformitarianism, the basis upon which scientists rejected the historicity of Genesis, are slowly giving way.
Praise Be to God!
