The following was posted on the Whitney FB page a few days ago. Anyone heading up soon, a pic or 3 of this would be appreciated. Measurements or something in the pic for scale would be helpful. It is not believed to be either radioactive or toxic, but ya never know about things up there (cue the Theremin):
Does anyone know the story behind that metal box thing beside the main trail, near switchback maybe 26 or 27? It looked kind of like a drawer from a 1950s era filing cabinet or something. Definitely NOT something even the least UL hiker would've carried in their pack, so I'm guessing it's from an old surveying trip, or was deliberately placed nearby to hold something and then got damaged? Unfortunately I didn't get a picture. Spotted on my descent 8/15/17.
