Abstract
Many aspects of geomorphology indicate that the Green River Formation (GRF) was deposited during the Flood. The massive deposition and erosion of the GRF immediately suggests the Flood catastrophe and not post-Flood processes. Pediments and the long-distance spread of well-rounded quartzites also points to the Flood. Furthermore there are many climatic problems if the GRF and associated formations were post-Flood. Based on multiple criteria, it is believed that the Flood/post-Flood boundary is in the 'late Cenozoic' over the western
