Missouri River approaching Cannonball River — Patrick Gass: October 16, 1804

clear morning, passed a creek on the south side. The timber
is more plenty than it has been for a considerable distance
down the river. The sand bars, gave us a great deal of
trouble, and much retarded our progress. In the evening a
short time before we encamped, we met with another hunting
party of the Rickarees. They had a flock of goats, or ante-
lopes, in the river, and killed upwards of forty of them.
Captain Lewis, and one of our hunters went out and killed
three of the same flock. We encamped on the south side.
This day we saw more than an hundred goats.
