All the dirt on an ancient earthen mound
The enormous earthen monument Poverty Point, built on a Mississippi River bayou some 3,200 years back, is an impressive feat of engineering. Hunter-gatherers moved more than 26. 5 million cubic feet (750,000 cubic meters) of dirt to create concentric ridges and several big mounds in what is today northern Louisiana. Now analysts say one of the most excellent earthworks at the site likely took shape in fewer than 90 days, built by hundreds of Native American laborers using a "bucket brigade" system. Archaeologists excavating parts of Poverty Point, which is now in the going to become a UNESCO World Heritage Site, analyzed center samplings and sediments from one of the massive earthen features called Mound A. Curiously, they discovered no traces of rainfall or disintegration throughout the building phase of the mound.

"It's likely that these mounds were built using a simple 'bucket brigade' system, with thousands of people passing soil along from one to another using some form of crude container, such as a woven basket, a hide sack or a wooden platter." |

Key:
- Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
- The Mean is meant to be an indicator of an individual's average comment sentiment.
- The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).
Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
