IY... ROCK. SHELTERS 
The analysis of rock shelters presents a fundamentally dif- 
ferent problem than do the open sites. Only small family groups 
could occupy them at a time thus remains are usually found 
in small pockets. The chances of obtaining stratigraphy are 
much greater in rock shelters than in open sites because the 
rock shelters afford permanent protection to many different 
groups of people over a period of time probably equal to the 
time that man has been in the region in some instances. Most 
of the rock shelters that we have investigated have stratified 
deposits, 
GROUP OF SMALL ROCK SHELTERS IN SIDE OF 
MISSISSIPPI RIVER BLUFF (LOCATION II) 
J*k, J82,. J83 
There are three rock shelters lying not more than 200 
meters distant from each other in the sides of the bluff of the 
Mississippi River. 
The most northerly of the group, J82 is a very small cavity 
only 2 meters across the face and less than 2.5 meters deep. 
A temporary irregular fireplace was found near the surface. 
Twenty centimeters below this was a round fireplace con- 
sisting of ash and burned clay. There were a few sherds, an 
imitation bear canine made from the columella of a Busycon 
shell and a small pebble hammerstone around the fireplace. The 
pottery was Herculaneum Cord Roughened but there were a 
few Imperial Plain sherds. 
J*1 a few meters south of J82 is 14 meters across and ap- 
proximately 8 meters deep. It contained a fireplace 80 centi- 
meters deep, very small and irregular. Pottery fragments, very 
few artifacts, mussel shells and animal bones were found in 
the original shelter floor at a depth of 140 centimeters.
