So, back to our little “flightseeing” tour.
Glaciers are made up of fallen snow that, over many years, compresses into large, thickened ice masses. It’s so strange to me that glaciers move, like really slow rivers. The ice erodes the land surface and carries broken rocks and soil debris far from their original places.
Moraines are created when the glacier pushes rocky debris as it moves. These long, dark bands of debris are visible on top and along the edges of glaciers.
“Kettle” lakes form when a piece of glacier ice breaks off and gets buried by glacial till or moraine deposits. Eventually, the ice melts, leaving a small depression in the land, filled with water. Kettle lakes are small, more like ponds.
The pilot pointed out that this hole was formed by the glacier. Weird, huh?
I thought this terrain was more “glacier-like.” I needed to remember that we were in the summer, not winter. (Never mind the snow provided by WordPress!)
All too soon, we were heading back to the airfield. I loved being in that plane and wished I was flying it.
Has anyone see the movie Into the Wild? It’s from 2007, but I just saw it at the library recently. That film really shows how isolated Alaska is. I could never live in a location that remote…how about you?
Great weekend, everyone!
