I probably need to measure it accurately and get a good estimate of
the weight.

~145 lb/cu. ft. for sandstone.
~7000 lbs?!

I think lifting it off the ground would be the easy part.
Moving it would be the challenge. Even if I had a trailer stout enough
to carry it, I don't think I could roll one under it, especially with
tripod legs to avoid.

Time to build a humongous offroad gantry crane!
