The trail up Mt. Hoffmann proceeds from left to right up the slope that's in the sun here. It doesn't look particularly steep, and in fact, it isn't. Somehow, though, when you're hiking uphill at 10,500 feet, it feels as though some cataclysm has turned the earth off its axis a bit, tilting the slope upwards just for you and scaring away all the oxygen into the bargain.
May Lake is just out of frame to the right but isn't actually visible from this spot (since none of Yosemite's lakes lie in glass tanks, you have to be at higher elevations than the lakes to see them).
