The Mystery of Whitehaven Beach. Geologists generally agree that Whitehaven’s quartz-rich sand has not come from a local source, because rocks in the area do not contain large quantities of quartz. The most likely explanation is that the sand drifted north along the Queensland coast, carried by prevailing sea currents, millions of years ago. Trapped by rocks and headlands, some sand accumulated to form the dunes of Whitehaven Beach. Sea levels rose and fell around the dunes as ice ages came and went. Over time, impurities were leached from the sand by fresh water, leaving it the fine, white silica you see today. The most recent rise in sea levels, about 10,000 years ago, brought the sea to the foot of these dunes, creating Whitehaven Beach.
