| 説明 | Mound Cemetery takes its name from the prominent 'Conus' mound whose construction was during the Adena period.Fortunately Marietta, unlike many other midwestern communities, still retains some of its prehistoric earthworks. This is due to the foresight of the Ohio Company of Associates who in 1788 named the mounds and decided to preserve large parts of these earthworks in public parks. The members of the Ohio Company actually undertook an effort at dendrochronology (tree ring dating)and harvested a tree from the top of the mounds. At least 400 years of growth was counted on that tree.The origin and disappearance of the prehistoric Moundbuilders has long been shrouded in mystery. 'Conus' is the burial place of chieftains. The mounds and earthworks were constructed between 800 BC and 700 AD. These early inhabitants were the first farmers and artisans in the Ohio Valley and Marietta was the site of a Moundbuilders city. |
