There was no other place to discuss Ingraham flats so I put it under Camp Muir. Ingraham Flats is another mountaineering "camp ground" located 1.5 miles passed Camp Muir. This site is generally occupied my climbers attempting to summit Rainier. It's a great place to practice crevasse reacue and general mountaineering skills. From Camp Muir, you will need to be roped up while traversing the glaciers to Ingraham Flats. The views are incredible so if you have extra time before summiting Rainier, I suggest staying overnight at Ingraham.
