Chinese Wall (Montana)
The Chinese Wall is a large cuesta that lies along the crest of the Lewis and Clark Range in Bob Marshall Wilderness Area in northwestern Montana, USA. It stretches from Junction Mountain northward for. It has an eastward-facing escarpment, high, carved by Pleistocene glaciers from westward-tilted, sparsely fossiliferous, Middle Cambrian limestones. At the base of this sheer wall, the limestones overlie Middle Cambrian shales and sandstones resting unconformably on late Precambrian sedimentary strata of the Belt Supergroup. The highest points on the wall are named separately as mountain peaks, including Junction, Haystack, Cliff, and Salt mountains. The Chinese Wall makes up part of the Continental Divide: water on the different sides of the wall flow into either the Atlantic Ocean or the Pacific Ocean.
Access
The wall is most commonly accessed through Benchmark Trailhead. It normally takes hikers multiple days to reach the wall, which is located about from the earlier trailhead. The Continental Divide Trail passes directly below the wall.There is a camping ban in place directly along the wall to maintain the relatively fragile ecosystem from overuse.
