Message 101 Admin posted Faith's image. I guess she (is that settled?) is asking why we don't see that sort of thing. The answer is that we do see that sort of thing, in radar images and seismic images and satellite images and borehole chains and what-not ... and these observations are obviously incompatible with a global flood. Faith's just tremendously overestimating the likelyhood of such features breaking through to view in a place like the Grand Canyon.
