Having been a student of sand (and sandstone), I fully appreciate this creator’s wonderful explanation of the diverse and beautiful nature of sand. In the video below, weathered grains of granite make their way from California’s Sierra mountains to the Golden Gate. Here in Colorado, there are endless ways to study the origin of sand. Our summer hikes to Gem Lake Trail in Rocky Mountain National Park reveal fractured and weathered granites- some of which simply crumple in your hand- the humble origin of sand from the Rockies.
