I spent most of the last nine days in the Grand Canyon, rafting down the Colorado River on the National Center for Science Education's 2007 trip. I met interesting people and made new friends, ate great food, and saw amazing sights. This was my third trip down the Canyon, but my first in the last two decades (my previous two were in August 1976 and June 1985).
This trip included the presentation of both creationist flood geology and real geology, but there was no contest--when you have hundreds of feet of successive ocean floor beds full of fossils of marine life that has lived and died, and a large variety of completely different kinds of formations that have clearly been deposited in different kinds of events, it's transparently nonsense to claim that it was all laid down in a single year-long flood.
