Glacier National Park dominates the western half of this 1964 survey, where the Continental Divide meets the Hudson Bay Divide. This intersection creates a unique triple-divide drainage system, where water flows toward the Pacific, the Gulf of Mexico, and Hudson Bay. The high peaks of the Swan Range and massive summits like Chief Mountain and Mount Jackson tower over glacially carved features including Lake McDonald and Saint Mary Lake.
