Apart from OV itself , Vidette Meadows , the moonscape camping spots just at the base of Forester (so beat up couldn't move an inch south

. This area is exposed and temps drop below 32. , Crabtree meadows
Last day was fun when i realized i couldn't make the summit in time. Holed up at a bivy site just after Guitar lake - seemed like a nice set up to summit the next day, and it was.
There are two bivy /tent sites that tend to fill up fast, one about 500 ft vertical from Guitar Lake and another 2000ft vertical from Guitar lake , just below trail crest/JMT junction. EIther can be used as launching spots for the summit.
Thanks for the prompt Steve, just fixed the Title to include Trip Report.
