Your panoramas should be studied carefully by our friends at the labs.

The middle tier is very interesting. There's a really neat "segmented worm" in the upper right quadrant of the image. Note all the "segmented worms" in the righthand hollow. There are worms and pieces of worms everywhere.

How do these things form?

Also, is that little wizened thing below and to the left of the sphere in the lower right corner a "failed" sphere?

As eaten away as this matrix material is, it hardly seems like rock at all.

Some of the void shapes in the top tier are distinctly angular. It's hard to imagine that they weren't occupied by crystals. Maybe there are some scattered on the ground...

These are really nice images!
