Although this heavy snow year presents a challenge, one has to keep in mind that it presents an opportunity as well. It will be up to each person to determine what that is for themselves. In the 60's, 70's, and even 80's there was typically much more snow in the passes at the end of August than a typical year now. I will grant you that it was much more compacted in general. As for me, my end of July off trail trip above Sierra Nevada treeline is on; I'm just probably bringing gear I haven't brought in a while. Give yourself extra time to negotiate hazards safely; have backup campsites just in case. It's all stuff you already know.
