It is going to be very cold spring weekend. The forecast for Whitney Portal Friday night is 17* F.
Let me give the 3-season light weight hikers turned backpackers for a weekend a tip, dry equals warm. As soon as your camp is set up get out of those sweat drenched clothes and into dry ones. If you are planning to cut your pack weight by skimping on clothing don't or Trail Camp will be a miserable experience.
Oh, if you have any kind of inflatable mattress, you best have a 2nd closed celled foam one to place under it. My Big Anges Air Core Insulated Mattress doesn't perform all that well in the twenties with no snow, let alone frozen ground or snow. This mattress is rated to 15* F.
Have a safe trip.
