Missouri River near Marias River approach — Patrick Gass: June 1, 1805

ing was cloudy, but without rain. We passed through a more
handsome country, than for some days past. It appears
more level and there are some good bottom on both sides
of the river, but not large; also a number of beautiful small
islands covered with cotton wood. We saw a number of
mountain sheep. Yesterday our men killed three of them,
that had remarkable large horns; one pair weighed 25 pounds.
We passed a small river on the North side about 11 o’clock.
The water is not so rapid to-day as usual, but continues high.
In the afternoon we passed a creek about 30 yards wide, and
several small islands. We went 24 miles and encamped ona
small island.
