Depending on the conditions, this climb can be 500' of thin to decent ice or mostly snow. If thin or mostly snow the route can be very run out. There are numerous variations. If you stay farther to the climber's left, you can belay in the line of trees that borders the route. If you stay towards the right you'll find islands of trees for belays.
Lots of options for the descent. You can rappel (recommend two 60+ meter ropes). You can downclimb on the climber's left or you can walk off to the climber's right down the gully that separates Emperor Slab from Chapel Pond Slab.
Starts a couple hundred yards to the climber's left from Chapel Pond slab. It can be seen from the road and is left of the gully that divides Emperor Slab from Chapel Pond Slab.
Bring mostly short screws (10cm) if the conditions are thin. A snow anchor/fluke might useful too. Generally the snow won't be deep enough to take a snow picket/stake.
