ing in a deep sink hole half a
mile away on the farther side of the hill. Into this depression pours
all the water that comes through a ravine more than 4 miles long,
receiving several tributaries on the way; thus draining several
hundred acres of steep hillsides from which storm water runs off
almost as quickly as from a roof. From the sink hole it passes into
the upper end of the tunnel, an opening 10 feet high and 20 feet wide.
Trash and drift around this inlet show that the water rises above its
top.

The lower opening of the tunnel is a beautiful, regular arch, 100 feet
wide and 50 feet high. For some distance in, the interior is so choked
with huge rocks, which reach almost to the roof near one side at the
front, that it resembles a great quarry. Gravel, sand, and driftwood,
including a large log 15 feet long, are piled on these rocks to a
height of 20 feet.

BROOKS CAVE

Brooks Cave, 11 miles southeast of Waynesville, has an entrance
through a sink hole in a level field. It is small and dark for some
distance back, and was never occupied.

Openings of this character are never the original mouths of caverns;
they are due to the roof falling in at a point where it has become
thin by wearing away from below.

RIDDLE CAVE

Riddle Cave is on John W. Schord's farm, near Wildwood. The entrance
is through a sink, similar to that at Brooks Cave, and is due to the
same causes. It could never have been occupied.

LANE'S CAVE

Somewhat more than a mile north of Big Piney post office is a cave
known as Lane's Cave. Near it is a smaller cave; also a rock shelter.
They are all small, high up in the cliff, hard to reach, and
unsuitable for living in.

DRY CREEK CAVE

A cave on Dry Creek, north of Lane's Cave, is small and almost
inaccessible. Never used.

HOUSE MOUNDS (23)

There is a group of house mounds, about 100 in number, close to the
site of the "Ranch House," which formerly stood near "The Falls" 4
miles southwest from Big Piney. Two other groups, north of this one,
carry the mounds for about 4 miles along a little valley, which
extends north and south about midway between Big Piney and Bloodland.
Most of the mounds, in all the groups, are on the slight slopes
bordering either side of the little stream--which sometimes ceases to
flow--but a few of them are on the narrow strip of level land along
the banks.

There is another group south of Bloodland. They were not learned of in
time to visit
