Glacial Lake Missoula Flood or
Lake Bonneville Flood
Sentinel Hill in Montana appears to have similiar striations as those on Weatherby Mountain in Eastern Oregon and those along the Snake River at Glenns Ferry, Idaho. Those in Oregon and Idaho were created by the Lake Bonneville that is known to have occured only once. Those on Sentinel Hill are said to have been created by multiple floods, The similarity seems to prove that there was only one Ice Age Flood in Montana, Washington and Oregon as described in my book. Another resource to learn about the Bonneville Flood is the book, Hydrology, Hydraulics and Geomorphology of the Bonneville Flood.

The Ice Age Flood
What caused the Ice Age and the resulting flood
I said in my book that I thought the age of the earth and the timing of the Ice Age was much less than the millions of years as claimed by many geologists and scientists. In his book "Frozen in Time" Michael J Oard deals with that issue. In Chapter Seven he provides evidence that the Ice Age was caused by the Biblical flood, often referred to the Genesis Flood or Noah's flood, that covered the entire earth and killed mankind and all of the animals except those that were on the ark. The Biblical Account of the flood can be in Bible in Genesis Chapter 7, Verses 17-20 also Genesis Chapter 8 Verses 1-18.
Another excellent book is Walt Brown's "In the Beginning - Compelling Evidence for Creation and the Flood." I recommend reading it as you ponder the issue of the flood.
I have provided a link to the account in Answers in Genesis. I would recommend it as you ponder the question. Michael J. Oard's book "Frozen in Time" can be purchased from Amazon or the Answers in Genesis web site along with many related books. I would recommend reading the book. It is great resource on Creation and Evolution. Another good resource is Ken Ham's Ultimate Answers Pack, a collection of five fascinating books from Answers in Genesis.
