Catching Up

2016.02.16  - After a hiatus and a power outage erasing an earlier edit, time for catching up. I need to build permalink pages too, but first what's new.

Hundreds of Geoglyphs Discovered in the Amazon

Currently, 440 geoglyphs are documented in both an Excel spreadsheet and a Google Earth placemarks file. The geoglyphs are placemarked, all except the smallest earthworks are outlined, plus visible ancient lines are highlighted. The webpage has been updated, including the most recent data files:

Turgai Steppe Geoglyphs - Kazakhstan Geometric Earthworks

The geometric earthworks of Kazakhstan have been in the news. Geoglyphs are found in various regions of the world, including the Asian steppe. Geoglyphs present geometric forms; circles, squares, crosses, ellipses, octagons, ovals, and more. Kazakhstan's impressive Ushtogay Square grabbed the attention of the world. Many earthworks remain to be discovered with high resolution imagery updates. I found new ones while examining the recently published Kazakhstan data and maps and building a placemarks file. Check them out in Google Earth, or hunt for new ones:

Newark Earthworks and Pinson Circle

2016.04.16 - Newark Earthworks is monumental, an outlier in scale of constuction. Archaeogeodesy research results confirm its prominence. Pinson Mounds in western Tennessee, the largest Middle Woodland mound complex in the Southeast, includes the second-highest mound in the United States. At 160 acres in extent, Pinson is larger than the Ohio earthworks complexes with the exception of Newark. In scale, Pinson Circle is equal to Newark's slightly elliptical Great Circle (1,163 by 1,189 feet). Today Pinson Circle has a surviving 141° arc section of a near perfect circle 1,190 feet in diameter. Pinson excavations evidenced inter-site exchange with flint bladelets from Flint Ridge, near Newark in Ohio. Pinson has even been called a Hopewell site.

I examined the inter-site spatial relationships of the monumental features at the two sites. The results support the interpretation of a lunar major alignment of Newark Octagon. The arc distance from the Octagon's Observatory Mound to Pinson Circle's centerpoint equals 6.7006° or 0.0186127 earth circumference. During the Hopewell era, years per lunar standstill equaled 18.6127. From Eagle Mound at the center of Newark's Great Circle to Pinson Circle, the arc distance equals 6.70514° (0.250000 s22). See more with companion Google Earth placemarks.
