North America was once covered by a glacier!
We built a nice house atop a glacial moraine outside Soldotna, AK in the 1990’s. One of the homes we owned outside Sandpoint, ID had bedrock exposures in the front yard that bore linear grooves from glaciers sliding over them. Our most recent build outside of Libby, MT is on the shore of what was Glacial Lake Missoula. Civilization exists wherever geology allows it. Libtards are so enamored of themselves that they believe that humans can exert control over the natural processes of the Earth. What conceited morons they are.
