Blackberry Hill is a Konservat-Lagerstätte of Cambrian age located within the Elk Mound Group in Marathon County, Wisconsin.

[1] It is found in a series of quarries and outcrops that are notable for their large concentration of exceptionally preserved trace fossils in Cambrian tidal flats.

[3] The strata at Blackberry Hill are known to belong to the Elk Mound Group;[4][5] however, the lack of good stratigraphic markers (i.e., index fossils) in some Blackberry Hill localities, coupled with uncertainties about the age range of the Elk Mound Group itself, make it difficult to assign a precise age to these strata.

[9] Ripple marks and numerous other sedimentary structures identical to those found on modern beaches abound on the strata surfaces.

The animal life of Blackberry Hill was, however, represented by several kinds of macrofossils, all preserved as three-dimensional casts or impressions,[2] including:
