The white band was about where the clouds were that day.

To get to Odaray Trail you hike from Lake O'Hara to Lake Shaffer Lake, and continue about 1/2 half way to Lake McArthur (Lake McArthur is further right of Lake Schaffer) than this picture shows and turn right and continue climbing.

The location of the Alpine Route is a wild guess, and most of the third section is hiddened behind Mt. Shaffer, so the route shown is not actually continuous. You return to Lake O'Hara from Shaffer Lake on one of two trails.

I also guessed where Wiwaxy Gap (mean't to show it lower) and Oesa Lake might be.
