On the 10th we embarked in the Clear Water River and proceeded down the current.

The hills, the banks, and bed of the river were composed of fine yellow sand with some limestone rocks.

The earth emitted a hollow sound and the river was divided by rocks into narrow crooked channels, every object indicating that some convulsion had disturbed the general order of nature at this place.
