The resemblance of certain objects from the Crystal River Mound in Florida to others taken from mounds of the Hopewell culture in Ohio was first noted by Shetrone in 1931. Willoughby discussed a certain type of design on a round copper plate, interpreted by him as representative of the foot of a bear, and commented upon the presence of such Hopewell-like objects as plummets of shell, stone, and copper, copper ear spools, and conjoined copper tubes. The resemblances between these widely separated mound groups are much more numerous than have been listed in any publication up to the present date, but the Crystal River Mound and other related mounds in Florida have been denied inclusion in the Hopewellian culture for the reason that most of the pottery found in them is not of the Hopewell type.
