Friday the 10th. Passed Chimney Rock this morning. This rock is situated about 2 miles to the left of the road and of the same kind of material as Court House Rock. It is about 150 feet high including its base which has the form of a pryamid [sic]. At the top of this the chimney commences which is about 5 or 6 ft. in diameter. It is not as high as it was last year (so say those who passed it then), it is constantly wearing away by the storms, which are severe. Came 15 miles to-day and camped in sight of Scotts Bluffs, so called from the circumstance of a man by that name having been killed there by the Indians.
