Muscatine County — Continued. 



Near Wyoming Hill Gass 39 describes a mound on a small area 

 of bottom land between and close to the confluence of two little 

 creeks, almost surrounded on every side by high bluffs, opening 

 in front toward the Mississippi River. The base is just above 

 high water mark. Oval in form; long diameter nearly 200 feet; 

 more than 30 feet height; it is small and rounded on top; thirty- 

 three layers of earth, clay, sand and gravel clearly defined; scat- 

 tered charcoal fragments, some large, through it. In the bottom 

 of the mound is an immense [tile of slabs of sandstone, two or 

 three inches thick and several feet across, disposed in layers of 

 which, the bottom one resting on the clay extend almost to the 

 outer edge of the mound; the next smaller and so on for about 

 20 layers to about 8 feet in height, ending in a very broad, flat, 

 pyramidal form. Is this really artificial?

Council Bluffs. Two grooved axes, taken from bluff deposits 

 one eight feet below surface, one twelve feet, both near Council 

 IJhiffs. Owned by Dr. Stillman.'^s 



Stillman explored the bluff i^ miles north of Council Bluffs 

 on the Mynster Springs road where a cut had l)cen made. An 

 opening about three feet across was driven into the bluff to a dis- 

 tance of four feet, and 5 feet below the soil surface. A large 

 fragment of an elk's antlers; a shoulder-blade, fashioned into a 

 rude implement; fragments of l)one; a ])ipe; a piece of deer 

 antler, 4^4 inches long, polished at one end; several flint scrap- 

 ers; potsherds; a charred corn-cob; several large mussel -shells; 

 many fish-bones ; several vertebrae; small bowlders showing fire 

 action; a stone paint moriar of rough red cpiartzyte, were 

 found. '3« This find was on the western face of the bluff, 40 feet 

 above the Missouri bottom, and not far from a lake that touches 

 the foot of the bluff just north of this point. Above the find 

 the bluff rises to a height of one hundred and fifty feet, with a 

 gradual slope to the crest. 



South of this point, a half-mile or so nearer the city, is an 

 exposure at a brick yard. It is at the mouth of a hollow or wide 

 ravine, extending back into the hills for some distance. Here, 

 under from 6 to 8 feet of bluff deposit, are ash-heaps of consid- 

 erable size, with bones, mussel-shells and pottery. '^s
