Not great. I arrive at Vegas very late on the 28th of June....Will be at Mt Whitney Portal on Wednesday early (AM) to pick up Permits.....our permits are for an overnight, starting Thursday the 30th. Not much time at all, and I live basically below sea level. Lone Pine Lake is about 10K, yes? If we don't spend the night before at Lone Pine, it will be over at Horseshoe Meadows....I guess....it will also depend on weather, conditions...etc.
