Additional mounds of Duval and of Clay counties, Florida; Mound investigation on the east coast of Florida; Certain Florida coast mounds north of the St. Johns river

by Clarence B. Moore

Structurally the mound was of considerable interest, the strata well defined. Immediately in a central position was a cone of white sand, surrounded and surmounted by the regular strata of the mound.

The stratification of the mound from the top downward, a little north of the center, was as follows:

2 feet 6 inches—dirty brown sand.

1 foot—dark sand with oyster shells.

1 foot—pink sand mingled with oyster shells and with white sand.

5 feet 8 inches—yellow sand.

7 inches—dark sand and oyster shells.

2 feet—light sand to yellow sand of the base.

At various points in the mound were pockets of sand artificially colored with Hematite.

The distance between the summit of the mound at the center to the yellow sand at the base, where charcoal and human remains were wanting, was 15 feet.
