The place today: Missouri River Breaks area
The country much the same as yesterday; until about 12
o’clock, when the bottoms became more extensive on both
sides of the river. There is still a small quantity of pine tim-
ber on the hills. We had some showers of rain in the fore-
noon; hail in the afternoon; and a fine clear evening. We
went nineteen miles and encamped on the South side opposite
an island.
