Porcupine Ridge is a prominent mountain ridge located in the Goat Haunt area of Glacier National Park, in Glacier County of the U.S. state of Montana.[3] This mountain is part of the Livingston Range, and is situated 1.5 mile east of the Continental Divide. Topographic relief is significant as the summit rises approximately 3,900 feet (1,200 meters) above Lake Frances in one mile, and nearly 5,000 feet (1,500 meters) above Waterton Lake in five miles. Precipitation runoff from the mountain drains to the Waterton River via Olson and Valentine Creeks. This geographical feature's name was officially adopted in 1911 by the United States Board on Geographic Names.[3]
