Comparisons

I've been going over some photos and I can't help but recognize similarities between certain rocks or features of rocks that I've see in different places. I'd like to put some of them up here, side by side, to highlight the similarities.

These are rocks that have similar shape.

In each of the first two photos, the rock in the center of the pile supports the rock above it, that is very flat. These supporting rocks have very similar shapes:




These next two take on an "upside down and backwards" look to the prior two. Although one is a boulder, the resemblance in shape of these two, I think, is uncanny.





This is all pure conjecture, but it sure is interesting!
