How does Denali compare with Rainier or Aconcagua?
Primarily it is a more physical climb involving heavy loads. It is a much longer climb but similar to Rainier in that you climb on steep snow slopes most of the time but obviously at a significantly higher altitude. You are using fixed ropes on the headwall above the Ranger camp at 14,200′ and you are pulling a sled with personal and group gear. Finally the weather can be extreme with brutal winds and cold temperatures.
