The personnel of this party is sufficient evidence of the wide-spread interest which was being taken at the time in the region of the Upper Yellowstone.
The party proceeded from Helena to Fort Ellis, one hundred and twenty-five miles, where they were to receive a military escort promised by General Hancock, at that time commanding the department in which Fort Ellis was located. The post order detailing this escort is dated August 21, 1870, and directs Lieutenant Gustavus C. Doane, Second Cavalry, with one sergeant and four privates, “to escort the Surveyor-General of Montana to the falls and lakes of the Yellowstone and return.” There is a significant absence in this order of any reference to geysers or hot springs; and the discreet post commander evidently did not intend to commit himself to a recognition of their existence on the strength of such knowledge as was then available. His incredulity was indeed largely shared by the members of the party themselves. Mr. Hedges subsequently said:
“I think a more confirmed set of sceptics never went out into the wilderness than those who composed our party, and never was a party more completely surprised and captivated with the wonders of nature.”
Lieutenant Doane, than whom no member of the expedition holds a more honorable place in its history, has left on record a similar confession.
The party as finally organized, including two packers and two colored cooks, numbered nineteen individuals. Thirty-five horses and mules, thoroughly equipped for a month’s absence, completed the “outfit,” and made altogether quite an imposing cavalcade.
August 22, 1870, the expedition left Fort Ellis, crossed to the Yellowstone, and ascended that stream through the First and Second Cañons, past the “Devil’s Slide” and Cinnabar Mountain, to the present north boundary line of the Park at the mouth of the Gardiner River. At this point they were within five miles of the celebrated Mammoth Hot Springs which are now the first attraction to meet the tourist’s eye on entering the Park. But the party kept close to the Yellowstone, instead of taking the modern route up the Gardiner, and missed this wonder altogether.
It was August 26th when the expedition entered the present territory of the Park. Lieutenant Doane and Mr. Everts, with one soldier and two hunters picked up on the way, rode in advance along the brink of the Third Cañon and across the high plateau between the Gardiner and Tower Creek, camping at nightfall upon the latter stream. In the broad open valley near the junction of the Yellowstone and East Fork, a small tepid sulphur spring gave them the first evidence of their approach to the regions of volcanic activity.
Next day, the remainder of the party arrived. Two days were spent in examining the beautiful Tower Falls, and—to our tyros in geyser exploration—the wonderful hot spring formations to be seen at that point. Here they also had for the first time glimpses of the Grand Cañon of the Yellowstone.
The party left Tower Creek on the 29th of August, and followed up the river over the east flank of Mount Washburn. As their progress lifted them rapidly above the surrounding country, a marvelously beautiful landscape unfolded itself to their view. Presently an interesting incident occurred, which shall stand here in Lieutenant Doane’s own language:
"Through the mountain gap formed by the cañon, and on the interior slopes some twenty [evidently a misprint] miles distant, an object now appeared which drew a simultaneous expression of wonder from every one of the party. A column of steam, rising from the dense woods to the height of several hundred feet, became distinctly visible. We had all heard fabulous stories of this region, and were somewhat skeptical of appearances. At first it was pronounced a fire in the woods, but presently some one noticed that the vapor rose in regular puffs, as if expelled with great force. Then conviction was forced upon us. It was indeed a great column of steam, puffing away on the lofty mountain side, escaping with a roaring sound audible at a long distance, even through the heavy forest. A hearty cheer rang out at this discovery, and we pressed onward with renewed enthusiasm."
