side of Little Piney. Two miles from the river is a cave at the head
of a little cove. The entrance, facing directly south and visible from
half a mile down the ravine, is 12 feet high and 75 feet across. The
rear wall, where the cave makes a turn at 150 feet from the mouth, is
plainly visible from the outside.

At 60 feet within water reaches from wall to wall, and a constant
stream flows along the left side. The talus at the mouth is of tough
clay with many rocks scattered through it, and much of it has settled
back into the cave. Water drips from many places in the roof, so that
no part of the floor is ever entirely dry.

Some broken flints and chips were picked up about the mouth and in
front of the cave, but nothing else could be found.

In dry weather there might be spots which would afford a resting place
for campers, but no continuous occupancy was possible.

HOUSE MOUNDS NEAR ROLLA (13)

Nearly 2 miles northeast of Rolla is the beginning of a little valley
which for a short distance is parallel with the Frisco Railway and
close to the right of way; it then turns to the southward. Along this
"draw" are numerous mounds, starting well toward its upper end and
following its course for nearly a mile. They lie along either side,
and reach into the tributary widenings. Most of them are on the flats;
but they are also scattered along the hillsides, those farthest from
the water having an elevation of about 50 feet above it. They vary
from 30 to 60 feet in diameter and from 1 to 3 feet high. In all, they
are scattered over an area of at least 100 acres.

HOUSE MOUNDS NEAR DILLON

Half a mile west of Dillon a ravine heads at the Frisco track, goes
south a short distance, then turns southeastward. Near the track
begins a group of mounds which reach for fully a mile along both sides
of the little stream.

There are more than 100, most of them small, though at least one is 60
feet across and 3 feet high.

HOUSE MOUNDS NEAR ST. JAMES (14)

At the northern border of St. James is a small shallow valley with a
northern and eastern trend, practically parallel with the Frisco
Railway, and for 3 miles or more not over a fourth of a mile from it
at any point.

Starting near the Soldiers' Home is a group of mounds which extend for
fully 21/2 miles down both sides of the valley.

Some are partly cut away by the stream, others are on the narrow flat
bottoms subject to overflow with every hard rain, still others a
