"Threatened by an approaching storm, the White Cliffs turn an ominous gray. 'It continued to rain almost without intermission last night and...our camp possessing no allurements, we left our watery beds at an early hour and continued our rout down the river,' [Capt. Meriwether] Lewis recorded of one of his own nights spent in this area. Upriver from the White Cliffs, the expedition finally arrived at a sight they had long anticipated—the Great Falls of the Missouri. Though damming has reduced the falls to one roaring rapid, it remains a 'sublimely grand specticle.'"
