The Discovery of Yellowstone Park

Along the trail, after leaving Fort Ellis, we found large quantities of the service berry, called by the Snake Indians Tee-amp. Our ascent of the Belt range was somewhat irregular, leading us up several sharp acclivities, until we attained at the summit an elevation of nearly two thousand feet above the valley we had left. The scene from this point is excelled in grandeur only by extent and variety. An amphitheatre of mountains 200 miles in circumference, enclosing a valley nearly as large as the State of Rhode Island, with all its details of pinnacle, peak, dome, rock and river, is comprehended at a glance.
