Above is looking out off of the shell mound. Below is looking back at the mound.
Below is an exposed wash-out of what the mound is built out of.
On another beach we found a shell mound. Mounds are 5,000+ year structures. They were either built just to create higher ground or they were created for purposes we have lost the faculties to understand. Could it be the previous inhabitants could sense subtle magnetic / electric fields and these structures heightened them? (Read: Seed of Knowledge, Stone of Plenty by Burke) Whatever the reason(s), this was a pretty breath-taking mound. It was 28 ft high, about 200 ft wide and, when it was first discovered, thousands of feet long. That is a huge earth structure! It was thought to be insignificant in the 50's and highway departments used it for fill to build roads. It is made out of shells, dirt, bones, tools, shards of pottery and more. In Seed of Knowledge, Stone of Plenty Burke writes that he hasn't found a sacred site like Shell Mound that was built at a time of prosperity. These were all built as last ditch efforts to save a dying culture and they worked! No one knows for sure if they were the seed energizers Burke hypothesizes.
Only an overhead shot could capture the scale of Shell Mound. The soil and fauna "looked" healthier on the mound. The trees were larger and more developed. The underbrush was less scrubby.
