Video of "Mole Mounds"
This drone video shows the pattern of "mole mounds" on 4k resolution. The drone was sent aloft from the public beach zone immediately west of Lot 3200 and flown north. The pattern starts to become evident at about 0:26 into the video and is very evident starting at 01:17 into the video. The video is processed at real-time (no speed up and no slo mo).
The mystery of the "mole mounds" was solved when a neighbor reported the pattern in the sand was crafted by a "bored looking twenty-something looking to burn off energy." No need to call Skully and Mulder.
The Truth is Out There.
