Gear left on Grand Teton-Owen Spalding-Labor Day Weekend

Think our group may have left the following gear somewhere between the start of the 5.4 section on Owen Spalding and the summit of the Grand: a trango sling  (gray) with a bunch of blue BD draws and home made webing slings 1in wide. It was back on September 3rd, so this is kind of a long shot, posting just in case.

Thanks!

I saw nothing on Sept. 10th. Three pairs of shoes were found....as was an iPhone in September.
