<b>Glacier-smoothed granite</b>
Glacier-smoothed granite
Glaciers smoothed this granite tens of thousands of years ago. The ice contained lots of sand, pebbles and rock dust that it picked up as the glacier moved along the solid rock. It worked much like sandpaper. In some areas the rock is shiny and often has marks (stripes) that indicate the direction the glacier was moving.
