Custer State Park, South Dakota, 1995
Photograph by Daniel R. Westergren
Ancient granite outcrops reflect in the still water of Sylvan Lake in South Dakota抯 Custer State Park as a lone fisherman awaits a nibble. Geologists calculate that the park抯 granite, into which the sculptures at nearby Mount Rushmore were carved, are about 1.7 billion years old, making it some of the oldest rock in North America.

南达科他州 考斯德(Custer)州立公园 森林之湖(Sylvan Lake),岸边露头的古老花岗岩,反射在静止的水面上,一如垂钓孤翁等鱼咬饵般.地质学家估计该公园的花岗岩,还有罗斯莫尔(Mount Rushmore)山附近那些雕刻好的花岗岩,都有17亿岁了.可说是北美最古老的岩石了.
