Mt whymper not good

Minus 27 degrees at the parking lot when we left at 7am. Bootpacked almost the whole way to the top as the snow was rock hard and we couldnt get grip on anything steeper than 35 degrees. Reached the summit at 1pm. Verry little wind if any through out the whole day, but very cold until reaching the col. The sun warmed us up for a bit before we skied down an absolute rockhard snowpack. Only some old avalanche activity was observed but nothing recent. Back at the car by 2pm and it was minus 15 degrees
