Crawlspace Soil

Has anyone seen soil in a crawlspace look like this (many small mounds throughout)? Do you know what causes this? The photo was taken today (April 25, 2016) in Sacramento…the soil was moist despite very little rain in the past month.

Buried heads


Fire Ants? :shock:

Only place I’ve seen anything like that was not in a crawlspace but in the desert outside Moab, Utah.
Was caused by microbial activity and took a long time to develop.
It’s called cryptobiotic soil.
