A mile east of Newburg a ravine now known as Pool Hollow, but formerly called "Strawhorn's" [Strawhan's] Hollow, opens into the right (north) 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.
