Rocks and Plants

More than 80 million years ago the granite rock formations you see here were molten rock beneath the surface. Cooling and solidifying, and later exposure to erosion left them in their present shape. Continued erosion has broken down the rocks providing minimal growing conditions only the most hardy desert plants can withstand. As the granite further erodes into more soil-like texture, a greater variety of plants can be established.
