Here are pictures of the chunk of caliche Tom brought to the surface when he explored RV's den.
not the best pic, but you can appreciate the size of the thing
side view, showing irregular shape. I don't know the position of it in the burrow, if it was up on its side, or not
close up showing some detail
finally, a close up showing the tight packed mineralized 'soil' - its all rock and tight grit.
All in all I think our soil is best suited for these guys to burrow, and I would really have to think hard about allowing a tort to burrow in anything else.
