In one of her latest blogs, the Grand Haven woman writes about the pleasures of the singing sands, how they were formed and her love of them.
"This sand is composed of quartz granules, dark-colored magnetite and other fine grains of rock," Spring wrote in "Michigan's singing sands" for her Dynamic Great Lakes Blog. "People love to walk in the so-called singing sands — it feels good underfoot. When a toe or shoe is dragged across the sand, there is a high-pitched sound or singing. This is due to the high quartz content of the sand."
She continues: "But to really learn about the dunes, you must visit Gillette Nature Center at the center of (P.J. Hoffmaster State Park), where there are displays explaining how the dunes were formed by actions of the glaciers and the west wind. The displays show dynamic dune succession: that is how dune plants and animals change over time."
