Ice dam proponents claim that the Missoula Flood occurred many times.
Geologists estimate that the cycle of flooding and reformation of the lake lasted on average of 55 years and that the floods occurred approximately 40 times over the 2,000 year period between 15,000 and 13,000 years ago.

So, not only did a catastrophic flood happen in the Scablands once, but around 40 times. And not only that, with a fairly consistent period of 55 years apart. And also at the exact same location. What an amazing sequence of events!
If 40 mega floods occurred here, some questions arise. Why here? Why not elsewhere? How did a glacier of this magnitude get created and dumped massive water with a period of 55 years 40 consecutive times? If 40 mega floods occured here one right after another, couldn’t some other mega floods have occured elsewhere on the planet?
From what I can tell, the only evidence for those floods is 40 layers found that could’ve only been deposited by a flood.
Waitt (1980) argued that each of about 40 Touchet beds resulted from a separate catastrophic flood.

Let’s say there were 41 floods. Why did the first 40 floods not erode the layers deposited from the previous flood? Did the first 40 floods erode anything at all? If they were catastrophic floods, why not? Why did the last one not deposit anything but simply erode everything away?
I’m going to have to pull out ole Occam’s razor here and ask, what is more simpler? One flood that occurred in my Wallula Gap dam theory, or around 40 mega floods that happen every 55 years over a 2000 year period?
