Thanks for the suggestions everyone. I hiked to Mammoth Pass Saturday morning (we didn't check into our hotel until 2:30 AM), Rainbow Falls Saturday afternoon, then Duck Pass Sunday. Duck Pass was amazing!
I probably won't get to the photos and trip reports until the end of the week (huge backlog of gear reviews to finish), but here are some instagram links:
