|Mount Kilimanjaro in the Distance|
|Mount Agamenticus in the Distance|
Actually, so does Mount Agamenticus, right here in Maine. Or at least it did. Mount Kilimanjaro started to form about 2.5 million years ago, and its last eruption occurred about 175,000 years ago. While this may be a long time on a human scale, on a geologic scale Kilimanjaro is a young Turk. Imagine Agamenticus on a similar boundary two hundred million years ago: the Maine coast is bidding a fond adieu to the North African shoreline after a short tryst as Pangea and Agamenticus rises 20,000 feet above the western coast. The volcanic center of this rift valley is widening and filling with the water that will someday become the Atlantic Ocean. As it does, streams and ice begin the shortening process of our once giant sentinel. Fast forward a hundred million years - the mountain is smaller, the ocean wider and about halfway to the form we now see. One hundred million more and the mountain is little more than 1/30th its former height, the spreading center nearly 1500 miles away.
