Social media users have been theorizing about what this bizarre, pulsating woodland soil could be: a marsh? An underground river? The beginning of a sinkhole? Wind lifting the interconnected roots of the trees? A hibernating Ent?
From the grainy footage, it's still hard to tell what exactly is going on. However, Nuttall has his own, fairly concrete, theory on the weird goings-on. He said in his Facebook post:
“The wind was blowing the trees on the hill a few days after the [remnants] of Hurricane Patricia, it was a strong west wind. I walked across a choppins [sic] that was logged a few years back. As I entered a patch of trees spared from clear cutting, I noticed the ground moving. I believe the larger trees are doomed to blow down but are currently spared, the smaller trees around them help hold each other up, as the wind pushes the trees into one another.
“I feel the trees didn't grow deep strong roots as they wouldn't be needed when surrounded by a forest, sheltered with strength in numbers unlike a tree found alone in a pasture. The punishing prevailing winds have taken their toll on the side hill, the roots have loosened and the mossy ground from the once shaded forest floor are giving way, soon to be toppled over.
“The ground is dry on the side hill, all gravel with shallow top soil for roots, not wet, no underground rivers.”
