With all the rain we are having, I noticed a weird spot in our gravel parking area. Periodically there are bubbles coming up from underground. (This is a gif made from a video clip)
Bubbles come up for a while, then stop for a bit. I knelt down and sniffed, but the only odor is wet gravel. There are no pipes underground there. I’m assuming it’s a natural phenomenon, any geologists out there?
