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.
