As a result, many gold prospectors have avoided the idea of beach mining. The process comes with extra labor and demands a lot of determination and patience for one to have reasonable and definite results. There are some pretty rich beach deposits out there though. In fact, some prospectors specialize in mining gold from beach sands.

The seemingly simple beach sand is actually the result of an epic natural process of mountain erosion and river transport. As mountains erode, they produce sediments including mud, sand, gravel, cobbles, and boulders, which then travel via streams and rivers to the sea, getting ground down along the way.

Waves and tides erode the rocks and particles further until they become sand. Environmentalist and author Rachel Carson summed it up: "In every curving beach, in every grain of sand, there is a story of the Earth." Sand is part of a cycle—one that often starts far from the shore. Experts say that the sand on every beach on Earth is unique.
