The top of Half Dome

The top of Half Dome, facing west

From the valley floor, it looks like the top of Half Dome is a knife edge where the hikers cling to each other to keep from falling, or at least to take someone else with them when they go. In fact, though, you could land an Ikea up here. It's not a place where you'd want to set your favorite bowling ball down, since Half Dome's summit has the posture of a swaybacked horse, but you can safely lie down and take a nap without fear of rolling over in your sleep and finding yourself in midair.
