Red Pipe Stone
[1874?]
Red Pipe Stone
Is found on Pipe Rock Creek in Barron Co. on land belonging to the Cornell University of New York (SW 1/4 Sec 27, T 35. R 10 W.) — It lies in strata from 6 inches to two feet in thickness, cropping out of the ground in some places. It was first mentioned in Owen's Report 1848 page 42 by Mr A. Randall with a section showing its dip (25°) and its association with "banded quartz". It is only referred to by Owen - "Mr Randall found at the pipestone locality 15 or 20 miles East of the Menomonee, beds partially metamorphosed, such as we usually find lying in close proximity to the crystalline formations".
Specimens collected here have all the external character of the red. pipe-stone of the Coteau de Prairie of Western Minnesota, so famous among the red men.
It probably belongs to the same group of rocks and has the same age as the [??better] sandstones & shales of Ashland County near Lake Superior - doubtless much older than the Potsdam Period.
Found also in other places.
It was used by aborigines for making pipes - being easily cut & polished when first taken from the quarry.
