I've heard the exact opposite. Real easy mountain to navigate.
It is not that bad if you rotate the map and make the top of the Sierra the top and Canyon and Eagle lodge the bottom , it makes more sense. Chair 14 is known as the back side of the mountain. They have a phone booth there if you get stuck there.
People have gotten lost but it is their own fault. It is like a big M , you need to zig zag to get from the lowest lodge to the highest main lodge . Take a trip if you are from so cal , you won't regret it.
