Mystery of the Megaflood
About 200 miles east of Seattle,
there is a large terrain called the “scablands”. This area is filled with valleys and hills
that appear as if they were made by water. It had been a mystery how these scablands
came about, because there was no evidence of any flowing or still water that
could have produced these large rocky masses.
J Harlen Bretz was a geologist who thought the scablands had come about by
a massive flood engulfing the area.
Others thought his idea was ridiculous, but Joseph Thomas Pardee helped
Bretz in his search for the answer. Pardee found an area in Montana where a
large lake had once been. He believed
that if the dam to the lake (which was a glacier) had been broken, the lake
water would flow to the area where the scablands are, and create the massive
hills and valleys. The only problem with
this idea was that something would have had to break the massive glacier of a
dam. However, this was later discovered
when a similar dam in Iceland broke.
