This video has many concerned about Yellowstone National Park as gas plume activity intensifies, leaving a dense cloud over the park.
Courtesy of Kat Martin2016, this video was captured on the 6th. To save time, fast forward to around the 3.00 minute mark as daylight helps to see the gas clouds.
This may just be a lack of wind over the park that is causing these clouds to remain static but even so, we have never seen such dense plumes like this before
Please comment below if you have any input as to why these clouds are so dense and static.
