Though the lakes, which formed at the end of the most recent ice age, may be Minnesota�s most famous features, the glaciated countryside disguises a much longer history of volcanoes and plate collisions�not surprising when you learn that Minnesota was at the active edge of the fledgling North American continent for several billion years.\u003cbr\u003e\u003ci\u003eRoadside Geology of Minnesota\u003c\/i\u003e steers you over glacial moraines and till plains to some of the state�s unparalleled geologic features, such as the Morton Gneiss, once thought to be the oldest rock on Earth; the St. Peter Sandstone, one of the purest sandstones in the world; the banded iron-formation, the source of iron for the Great Lakes steel industry; and the ancient shorelines of Glacial Lake Agassiz, one of the largest glacial lakes ever to have existed in North America. The book�s introduction presents an overview of Minnesota�s geologic history, and forty-two road guides discuss the landforms and rocks visible from a car window and at nearby waysides and parks, including Pipestone National Monument, Grand Portage National Monument, and Voyageurs National Park.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAbout the Author\u003c\/b\u003e\u003cbr\u003e\u003cb\u003e\u003ci\u003eOjakangas, Richard W.:\u003c\/i\u003e\u003c\/b\u003e - Richard W.
