Montana River Series - Missouri River

“Though the first people to gaze upon the peaks within the Gates of the Mountains Wilderness were Native Americans groups who passed through the region leaving pictographs, the first person to record the place in written history was none other than Meriwether Lewis, who upon seeing the area’s precipices, wrote that “from the singular appearance of this place [he] called it the gates of the mountains.” From that written record came the area’s name, and today, Gates of the Mountains Wilderness is one of the most recognizable landmarks on the Lewis and Clark Trail.”
