Odd looking dirt adjacent to foundation

While renovating my Dad's deck we pulled up all the deck boards. We were astonished to see a ~1' wide hole in the ground in the corner of the deck adjacent to the brick wall. It was odd, but could not figure it out. We just filled in the hole and finished the deck.

Now a year later I was leaving stepping off his deck down the sidewalk and noticed the dirt was all undulated. Sort churned looking. If it were liquid it would look like water boiling. There was also a lot of moss all around. All this adjacent to the same brick wall as described above. I wish I took a picture.

I went into the crawlspace. The ground was dark brown (moist) under the vapor barrier. No actual liquid water. The pipes in that area all looked dry.

Heaving dirt and moss next to the foundation. Any ideas?

It probably was an animal that dug the original hole. Who knows if something else have made the soft dirt their home or if the weird look is caused by weather.

Here are some photos. The first is the dirt abnormality I am speaking of. Notice the heaving of the earth along with all the moss. I could be wrong, but I really don't think this is an animal digging.

The second photo is taken just to the left of the first on the same wall.


Someone asked my location. We are in the South. Just North of Nashville, TN. Summers are hot and humid. This wall is on the shady side of the house if it has anything to do with it.

It could be a variety of things. Animals like voles & moles as well as frost heave or just different soil.

So the moss is just what you get in a shaded area!

I have areas where the wood chips have all sort of clumped together then in the winter when they freeze and heave they break up into "chunks".

You would have to dig it up but I had to look hard to see anything that seemed odd!

Agree on the moss. I have a lot of the stuff on the shady side of my house as well. As far as the heaving, it sounds like this may be the natural freeze/thaw cycle.

Thanks for the sanity check guys. I can tell my Dad to stop worrying!
