Gates of the Mountains Wilderness
Two sons of Chevalier Vendrye, the French explorer, passed through the area known as the Gates of the Mountains as early as 1742. They were probably the first white men to gaze upon its precipices. However, it was Meriwether Lewis who was responsible for naming the landmark and was the first to leave a record of his passage "from the singular appearance of this place I called it the gates of the mountains." The Gates of the Mountains, as it is known today, is one of the most widely recognized landmarks of the Lewis and Clark expedition.
