You know how the hills have eyes? Well, this forest in Nova Scotia has a FINE set of lungs on it. What makes this video even freakier is the fact that it was taken on October 31st... Fair play to hiker Brian Nutall who stuck around to take the footage (albeit in the WAR... *tisks*)
It starts off subtly enough, and really takes off around the 1:20 mark.
If you're still with us, and haven't passed out in amazement, there is a logical explanation for this phenomenon. A commenter under the video on YouTube had this theory (because their word is always gospel): "wBryang: This is a video of tree roots doing their job. The ground is soft, the wind is blowing the tree tops, which is tugging at the roots as they hold the trees upright. Cool video."
