Not usually magnetic in and of itself, black sand can and will become magnetized in the presence of another magnet. As each tiny grain of magnetized black sand becomes a (temporary) magnet itself, the magnetic field in that spot gets amplified, and more black sand gets attracted—ultimately creating the porcupine-like spikes that you see here.

Sand at Great Sand Dunes is made up of a variety of minerals, as can be seen if you look closely at a pinch of sand. One of the more obvious and interesting components of the sand is magnetite, a mineral that has eroded out of the nearby Sangre de Cristo Mountains. This black mineral is composed of iron oxide, so magnets are able to pick it up.
