From the Golden Gate to "Dear Old Norris"
On August 20th, our travelers left Mammoth Hot Springs and traveled through Yellowstone's "Golden Gate," stopping at Apollinaris Spring before arriving at Norris Geyser Basin.
Golden Gate, four miles south of Mammoth, is located along Glen Creek between Mammoth Hot Springs and Rustic Falls, a canyon running between Terrace Mountain and Bunsen Peak. Guptil's 1890 Practical Guide descirbes it as "a rugged pass betweent he base of the lofty elevation of Bunsen's Peak and the southern extremity of Terrace Mountain, through which flows the west branch of Gardiner River. The sides of these rocky walls, which extend 200 or 300 feet above the roadway, are covered with a yellow moss, suggesting the appropriate name the pass bears. The pillar at the east entrance, some 12 fee high, was oriainally a part of the canyon wall."
Apollinaris Spring would have been roughly halfway along the road between Mammoth and Norris, a good stopping point.
Emily Averell referred affectionately to Norris Geyser Basin in later letters; this building is otherwise unidentified.
