(Saw it before you exceeded your bandwidth)It is not a scud, or a rocket motor. It looks like it might be a storage system, like that used for air dropping or cacheing supplies.

Yeah, that's my thought too, that they look like storage tubes. In the even-larger version I'm looking at here, it's also obvious that the two tubes are also resting inside a tray of sorts.

The curious question, of course, is why they were buried.

Agree. Looks like a cache tube of some type. My guess is 10' long, 12" diameter.
