My guess **potential spoiler**
The SHIELD team that found the hammer at the end of Iron Man 2 couldn't move it, so they built a research structure/tent/building of some sort around it. This is Thor breaking in (maybe set off some kind of overhead sprinkler system, looks wet in there) and is retrieving the hammer. Maybe pulling up some of the ground with it for some weird superhero-Norse-God-reason.
