SCULPTURED ROCK AT TREMPELEAU, WISCONSIN. 
T AST November, whilst surveying mounds in the upper Missis- 
sippi valley, my attention was called to some rock sculptures 
located about 2)^ miles north-west from Trempeleau, Wisconsin. 
There is at the point in question an exposed ledge of the Potsdam 
Sandstone extending nearly one-eight of a mile along the east 
side of the lower mouth of the Trempeleau river, now known as 
the bay. Near its north end there is a projection extending out 
about seven feet from the top of the ledge, and overhanging the 
base about ten feet. The base of the ledge is forty feet back 
from the shore, and the top of the cliff at this point is thirty feet 
above the water. On the face of the projection, and near the top, 
are the sculpture figures referred to. 
No drawings or descriptions of these fine specimens of ancient 
work having ever been published, I thought it best to copy them 
for the inspection of archaeologists in a printed form. Whatever 
distinct markings were originally cut upon the face of this rock 
are doubtless there now, and the group as traced is complete and 
entire, and in its primitive condition, for it has not been mutilated 
by man nor perceptibly injured by exposure to the elements. 
Great care was taken to obtain correct tracings, the size of nature, 
and these having been reduced by pantograph the copy remains 
an accurate facsimile of the original. 
The centre part of the rock projection on which these figures 
appear, faces to the west, the sides falling back at a somewhat 
obtuse angle to the parent ledge. Owing to the horizontal extent 
of the space covered by the carvings they cannot well be shown 
in one connected drawing, so they are divided here for conveni- 
ence into three groups of nearly equal size. The following 
detailed description accounts for all the separate forms, and they 
are numbered in their natural order from left (north) to right.
