Never got around to uploading these yesterday.
Here's some of what I've got to work with:
Those aren't actual layouts I'd stick with. Just showcasing rock. Have actually been saving them for another 45-F or 60-F layout - specifically the tall rock.
Leftover lava rock:
UPDATE: Most of the lava rock chucks are fist-size or larger.
Also plan to dig through my driftwood stash to see what I can find/maybe order more.
