Alternative Routes Through the Alaska Range

I had a fun conversation with an ITI veteran about alternative routes through the Alaska range if Rainy Pass and Hells Gate Pass aren't available for some reason. This map shows two such alternatives: Simpson Pass and Goodman Pass. The theoretical case for taking one of these routes occurs when you are facing a choice between extreme avalanche danger in Rainy Pass due to a heavy snow or 30 more miles and sketchy open water through Hell's Gate.
