ourth of
a mile from these are two others; and farther back still more of them.
All are now destroyed. They were the usual conical heaps of stone, 18
to 20 feet across.

HOUSE MOUNDS (41)

A group of house mounds extends for half a mile eastward from Rich
Fountain, along the valley of Brush Creek. They are fully 100 in
number, and it is said there were formerly many more which are now
leveled by cultivation. The ground is low, in some places swampy, so
that water or mud surrounds many of them after a heavy rain.

"INDIAN FORT" (42)

This structure, also called the "Indian Lookout," is located on a
bluff facing the Osage, half a mile below the "Painted Rock," and near
the buildings of the Painted Rock Country Club, of Jefferson City.

Except for a slight projection or offset at one side, which contains
an opening or doorway, it was practically identical in appearance with
the vault graves along the Missouri River bluffs, described in Bureau
of American Ethnology Bulletin 37; or else with those on Big Piney
River in Pulaski County. It is formed of sandstone slabs, once laid up
in a wall but now scattered in confusion as if fallen or thrown down.
Apparently it measured about 32 to 35 feet outside and 12 or 13 feet
inside.

COLE COUNTY

NATURAL BRIDGE CAVE

This is at the top of a bluff facing the Osage, one-half mile below
the Rock Island bridge. It is only 10 feet wide and the same in
height, and extends back 20 feet to a narrow passage which is almost
closed by stalagmite. The site is difficult to reach, but disclosed a
few fragments of pottery and some shell. The earth of the floor
ascends rather steeply to the rear and contains many large rocks. It
was only a camping place.

MORGAN COUNTY

SPEERS CAVE

On the Brown property, 7 miles southeast of Stover, is a reported
cave, which proved to be a natural tunnel 400 feet long. The drainage
from several farms passes through it from ravines above. The lower
entrance is 40 feet wide and 50 feet high, the upper entrance 20 feet
wide and 10 feet high.

Natural bridges and tunnels of varying lengths and widths are rather
common in this part of the Osage Valley.

HOUSE MOUNDS (43)

Southeast of Stover, beginning at the edge of the town, is a group of
house mounds extending over an area having a very irregular outline,
but fully half a mile across in any direction. They vary from 20
