I just returned.

In past, I have gone from Guitar Lake over summit to TrailCamp with just 1 qt

this time took 1.5 qts to go from TrailCamp to summit to Trailcamp. Loaded up 1 qt there for the rest of the way to WP.

Cool start at 6 am and partial clouds in AM, mild storm in pm. Sweating was not a problem. Neither was water. Thirsty, yes, but you are not gonna die without 4 heavy qts for only part of a day. Go light.
