In Tuolumne Meadows, Yosemite Nat. Park California. Lembert Dome stands above everything else for miles around, and was left standing by a glacier which was deeper than the dome itself thousands of years ago. It eroded away the sediment and softer rock, but left the harder granite, polishing its surface as smooth as glass. You find this "glacial polish" all over the area, and you can still see the grooves and scratches from the rocks caught in the ice, a testament to the power of the glaciers.
