Lewis, July 18, 1806
Friday July 18th 1806. We set out this morning a little before sunrise ascended the river hills and continued our rout as yesterday through the open plains at about 6 miles we reached the top of an elivated plain which divides the waters of the rose river from those of Maria's river. from hence the North mountains, the South mountains, the falls mountains and the Tower Mountain and those arround and to the East of the latter were visible. our course led us nearly parrallel with a creek of Maria's river which takes it's rise in these high plains at the place we passed them; at noon we struck this creek about 6 ms. from its junction with Maria's river where we found some cottonwood timber; here we halted to dine and graize our horses. the bed of this creek is about 25 yds. wide at this place but is nearly dry at present, the water being confined to little pools in the deeper parts of it's bed. from hence downwards there is a considerable quantity of timber in it's bottom. we passed immence herds of buffaloe on our way in short for about 12 miles it appeared as one herd only the whole plains and vally of this creek being covered with them; saw a number of wolves of both speceis, also Antelopes and some horses. after dinner we proceeded about 5 miles across the plain to Maria's river where we arrived at 6 P.M. we killed a couple of buffaloe in the bottom of this river and encamped on it's west side in a grove of cottonwood some miles above the entrance of the creek. being now convinced that we were above the point to which I had formerly ascended this river and faring that a fork of this stream might fall in on the Northside between this place and the point to which I had ascended it, I directed Drewyer who was with me on my former excurtion, and Joseph Fields to decend the river early in the morning to the place from whence I had returned, and examine whether any stream fell inn or not. I keep a strict lookout every night, I take my tour of watch with the men.
