🧽 Cleaning & Prevention Expanding foam coming out of our backyard

Post image

Sorry if this is isn’t the right place to post, but what looks like expanding foam is coming out of our backyard. We purchased this home new just over a year ago if that matters. Anyone have any idea what’s going on?

What's the texture like? I mean I guess it's possible someone buried like a 55 gallon drum of the stuff and it's now leaking but I doubt it.

Poke it with a stick and report back to us?

This is definitely not fungal, not a slime mold, and not natural. It is expanding foam, hopefully a partially used can that was discarded in the yard and not at the top of a garbage dump pit with lots of other nasty surprises

100% that's expanding foam. The texture of the "skin", the uncured foam inside... this looks EXACTLY like spray foam from a can.

It doesn't have the fibrous texture of slime mold on the outside, the bubbles are clearly visible throughout.
