Two day trip. Camped at 5900' at base of Colonial Glacier, below Pyramid Peak. Steady snow started at 5200'. Traverse below Pyramid Peak was on snow. On the climb, we went too far up our first gully and had to drop down 100', go left over an arete onto the SW slope and scramble ledges to the "notch". Cross the notch and then go right into the final gully that leads to the top.
