Geocache Description:



































Visiting any Earth Cache is more than just "Logging A Find". It is an "Earth Science Lesson", and I hope you will enjoy mine.

The shaping of Michigan's geological landscape began more than one million years ago, during the great Ice Age. Michigan’s features were sculpted by four massive continental glaciers scouring across the Midwest. Michigan experienced the last great ice sheet, known as the Wisconsin Glacier, about fourteen thousand years ago. This huge ice mass was a mile thick and almost four million miles square. Its northernmost head touched Hudson Bay, and its icy tongue reached toward the banks of the Ohio River. As this "river of ice" crept over the underlying rocks, its base scraped millions of tons of earth like a giant bulldozer over the land. This debris composed of soil, pebbles, cobbles and boulders was pushed forward, grinding rocks into many various sizes and shapes.

Ice Age mammals inhabited Michigan then: mammoth, mastodon, caribou and giant beaver. Human hunters came into Michigan to stalk and kill these big game animals for food, fur and other necessities. The Paleo (ancient) Indians were believed to be the first humans to visit what is now Michigan. This conglomerate(puddingstone) boulder was unearthed by the Department of Public Works recently during excavation of a site adjacent to the St. Joseph River. The difficulty/terrain ratings were determined using www.clayjar.com.
