Even this effort proved abortive, due to Indian unrest and the failure of the military at Fort Ellis to furnish an escort. However, there were several men living at Diamond City on the Missouri River, forty miles below Helena, who were enrolled and waiting to join the Helena party. When word arrived of the postponement they decided to set out by themselves. This little expedition consisted of Hon. David E. Folsom, C. W. Cook, and William Peterson. Folsom and Cook were unusually intelligent men, with large experience in ranching and mining affairs. They were capable of executing a purposeful exploration of this character. Mr. Peterson’s precise status is not so well known. He was born in Denmark, served many years as a sailor, came to Montana as a miner, and later made a modest fortune as a stockman in Idaho. He was no doubt a resourceful member of the party, but his educational deficiency prevented him from making any contribution to the literary side of the enterprise.[120] They left Diamond City on September 6, after making arrangements to be away for six weeks. Their provisions and armaments were adequate for any emergency which three men might be expected to meet and survive. They had three riding horses and two for the packs. Among the usual camping equipment were listed a field glass, a pocket compass, and a thermometer. Bozeman was their last station of supply. From there they ascended a tributary of the East Gallatin River, and crossed the divide onto the headwaters of Trail Creek, which lies on the Yellowstone drainage. By September 14 they were at the junction of the Yellowstone, near Tower Falls. They followed the East Fork of Yellowstone River (now Lamar) for a day and then doubled back to Tower Creek. The scenery at this point intrigued them: ... Yesterday we caught glimpses of scenery surpassing in grandeur anything we have before seen so we concluded to lay over one day and give it a more thorough examination....[121] They were speaking of the overhanging cliffs and the second canyon of the Yellowstone directly beneath, also of the classic falls on Tower Creek. They reached Grand Canyon on September 21, after two weeks’ travel. From there they journeyed to the extreme west end of the lake and thence to Shoshone Lake, which they mistakenly considered the head of Madison River. Here they saw species of rare aquatic fowl, such as the whistling and trumpeter swans. Crossing the Continental Divide, which they called the “Dike,” they emerged into the Lower Geyser Basin. They made precise observations of the geysers and hot springs throughout the area and were enthusiastic over their performance. There was no lack of appreciation in this party.
