Access Wayside: Evidence of Ice
Transcript
At Jordan Pond House, a panel positioned along the deck railing displays a wayside exhibit entitled "Evidence of Ice."
The exhibit's title appears in the sky over an aerial view of Jordan Pond surrounded by vibrant green mountains. Labels identify Penobscot Mountain, North and South Bubble mountains, Pemetic Mountain, Cadillac Mountain, and Eagle Lake in the distance. Dotted lines indicate a U-shaped valley and moraine. An arrow points to Jordan Pond House: "You Are Here."
A pair of images show the terrain - one with a glacier, the other with a lake where the glacier had been. An arrow points to a rocky shoreline: "Glaciers pluck and carry rocks as they advance and leave debris behind - a moraine - as the ice melts."
More text reads: "Look for glacial evidence as you travel about the park. Notice the north-south alignments of ridges, valleys, elongated lakes, and coves created by rivers of ice."
An inset photograph shows a hiker standing on a cliff. "Carved by glaciers, sheer drop-offs on the Jordan Cliffs trail require hikers to scale rung ladders to the summit of Penobscot Mountain."
Text reads: "Mile-thick glaciers shaped the view in front of you. Over the last two million years, a series of ice sheets flowed from the north following old riverbeds and scouring the rocks of Mount Desert Island. Glaciers smoothed the mountains' north slopes, stripped huge chunks of rock from the south slopes, and cut U-shaped valleys. As the glacial ice melted in this valley, it left behind a mound of rock, gravel, and sand called a moraine. Water collected in the deep trough behind this natural dam—now covered with grass—creating Jordan Pond."
