We are heading up Oct 3/4th for a first attempt of Whitney via the Mountaineer's Route. I am hoping to shave a few ounces here and there, and was wondering if I can leave my tent stakes at home. By the look of the photos of UBSL and Iceberg Lake, it appears I would do better pitching my tent with medium sized rocks vs. traditional stakes. Any tips from the many veterans on here are greatly appreciated.
