So Odahviing dropped me off in Savngarde. I quickly killed two dragons, took the scales and bones, and was suddenly way over-encumbered. I decided to store a lot of my stuff onto one of the dragon corpses. I saved it there and have no saved over that specific save. I've since defeated Alduin and am now back in the regular realm of Skyrim.
My question is, is there anyway to get back to my stuff at the beginning of Savngarde? Can I call Odahviing and have him fly me back over there? Can I get back to the Hall of Heroes somehow?
