A Rainbow of Sands
Summer brings to mind images of beaches with warm yellow sand, but there's actually an entire rainbow of unique-colored beaches. Let's start with red … Cabot Beach, located near Malpeque at the northern shore of Canada's Prince Edward Island, boasts clay-red sands. The beach's amber hue comes from soil that contains a lot of rust. Prince Edward Island was formed on a sedimentary bedrock of soft sandstone that produces the rich, red soil.
