A Magnet On A Sand Dune, Great Sand Dunes National Park and Preserve
How many of you have hiked the dunes at Great Sand Dunes National Park and Preserve and noticed black patches or black ripples in the otherwise beige palette of the soft sand? What you are seeing are black magnetite grains in the sand. Magnetite is magnetic, and if you place a magnet on the sand, you'll pick up clumps of black magnetite grains. For real, and not an April Fool's joke! Cool, right?
