I quite doubt this will move since it's an un-heated structure built on top of 2 feet of gravel: any water that gets in which could cause frost heaves and subsequent movement will simply drain away fa enough that freezing won't be a problem. Building on gravel is somewhat like building a rubble trench foundation, or to lesser degree, like building on top of ball bearings.

They're nice, but since Force=mass times velocity squared, how does a 15 ounce titanium hammer have the same impact as a 28- ounce steel one?

I certainly would be willing to test this in the field, of course :-)
