Journal Entry 1805 Sep 12: "The road had been very bad during the first part of the day, but the passage of the mountain, which was eight miles across, was very painful to the horses, as we were obliged to go over steep stony sides of hills and along the hollows and ravines, rendered more disagreeable by the fallen timber, chiefly pine, spruce pine and fir."
