Overton Johnson and William H. Winter, Route across the Rocky Mountains with a Description of Oregon and California (1982)
“ The valley of this stream is high rolling prairies, and is very fertile. Its bottoms are wide, and there are numerous branches coming in from both sides, on all of which there is timber in most varieties found West of the Mississippi, some of which is good. Ninety miles above our crossing, we came to and crossed Big Blue River, one of its main branches. Here the Emigrants came up with us, and it was late in the night before their last wagons got over. This region has the character of being the residence of inhabitants introduced themselves in a manner that was by no means agreeable. ”
