Gardner River
It rises on the slope of Joseph Peak, Gallatin Range in the northwestern part of the park, and winds southeast through Gardner's Hole, a broad subalpine basin which is a popular trout fishing location.[5] The river continues north through Gardner Canyon and empties into the Yellowstone near Gardiner, Montana.The river and the town of Gardiner were named for Johnson Gardner who was a free trapper in the early 19th century.[7] Both these expeditions did not explore the Gardner and thus did not encounter the geothermal features of Mammoth Hot Springs.The 1871 Geological Survey of the park region by F. V. Hayden did explore the Gardner and describe Mammoth Hot Springs, but the Mammoth area itself was named by an illegal concessionaire, Harry R. Hohr, who tried to claim land in early 1871 in the newly explored park region.
