One of these ancient flood boulders stands firm in the middle of the stream channel, just below the lower edge of the pool dam at the foot of the fall nearest our camp.

这些古老的洪水巨石之一稳固地矗立在河道中间，就在离我们营地最近的瀑布脚下的水坝下缘下方。

The rock here is black metamorphic slate, worn into smooth knobs in the stream channels, contrasting with the fine gray and white cascading water as it glides and glances and falls in lace-like sheets and braided overfolding currents.

这里的岩石是黑色变质板岩，在河道中磨损成光滑的旋钮，与精细的灰色和白色瀑布形成鲜明对比，因为它在花边般的床单和编织的折叠电流中滑动、扫视和落下。
