0002552: Cave-in causes sand soil layer to change to loamy sand layer.
I have dug a 5x5 hole deep down to the 3rd cavern layer. I then supported the 5x5 sand soil layer above this stair well with a support and cleared out the hole, changing all up/down stairs to down stairs to force them to collapse during the cave-in.

Upon collapse via a lever the 5x5 block comes crashing down to the cavern bottom but it's soil type has changed from sand to loamy sand.
1. Dig a big hole under some soil.
2. Cave-in soil.
It's worth noting that a I had already forced a previous 7x7 cave-in in the 2nd cavern to breach an underground sea. I don't think it's related but who knows.

Loamy Sand is also the soil layer underneath the sand layer but it was mined out underneath the sand.

I have modded the game slightly, adding a single new ore (which appears correctly) and some misc creature edits.

Save available.
No tags attached.
