Sulphur Mountain, Wyoming

August 25, 1877 - Helena tourists camp near here
Sept. 2, 1877 - General Howard abandons wagons

Sulphur Mountain rises only 300 feet above the road but is still the highest point on this side of Hayden Valley. It made for a good lookout for a group of ten men from Helena who were touring the Park on August 25, 1877.

“We were just on the point of leaving the [Sulphur] Springs, when Duncan came running down from the top of Sulphur Mountain, exclaiming, “There’s a d--n big party of tourists, or else a big band of elk, ahead!” Wilkie said – “Yes, your elk will turn out to be trees, like all the rest of the game you see.”
After traveling 3 or 4 miles the boys began to grow uneasy. We could see something alive coming, but did not know what it was…
We traveled on…and, on reaching the top of a small hill, saw a large camp across the Yellowstone. 
Duncan exclaimed: “Indians! Indians! My God, it’s Indians!” He wanted us to backtrack…
We traveled back at a very lively rate for five or six miles to Sulphur Springs, where our scare seemed to subside a little…We then found a beautiful and safe camp.” 
– Ben Stone (tourist, Helena party)

When General Howard reached this point on September 2, they decided to abandon the wagons and carry what supplies they could.

“…though the trail did lead in the right direction, it took us over such fearful steeps, and across such deep and rough ravines, with precipitous banks, that it seemed utterly hopeless for our train of supplies ever to get through. These difficulties being in view, the troops gave up the wagontrain and took what provision they could carry with the packtrain, and went on to cross the Yellowstone at Baronet’s Bridge.”
– General Oliver O. Howard
