This video shows a long linear mound. Sorry about the quality of the video. The mound is snow covered and the brush around the mound made taping difficult. I wanted to document this type of linear mound. It is 40 feet long and points in a NW to SE direction. There is a round stone pile 20 feet East of this and these piles are part of a line of stone piles that extend for 3/4s of a mile.
