There is a lot of mystery and romance about Alaska. As a boy I pictured it as a land of ice and snow. It took a long time to dispel this illusion, to realize that grass and flowers abound clear to the Arctic Ocean and that much of Central Alaska is wooded. Far from being ice covered, geologists now tell us that the region was not even ice covered during the last glacial epoch when tremendous ice fields extended as far south as Iowa.
