There are nine named
plateaus in
Yellowstone National Park. These plateaus are part of the much larger
Yellowstone Plateau and dominate areas in the park south and west of the
Gallatin and
Absaroka mountain ranges. Four of the plateaus are from
rhyolite lava flows that occurred between 110,000 and 70,000 years ago.[1]
Gallatin Range as viewed from the Blacktail Deer Plateau
Traversed by the Mammoth to Tower section of the
Grand Loop Road, Blacktail Deer Plateau is one of the most accessible plateaus in the park. Blacktail Deer Plateau takes its name from Blacktail Deer Creek which flows off the plateau. Named by prospectors well before the park's creation in 1872, the name is probably attributable to the then prevalent
Blacktail deer of the area.[3]
The Buffalo Plateau straddles the Montana-Wyoming border north of the
Lamar Valley and west of
Slough Creek in the park's northern range. Named in 1870, before the park's creation, by prospectors Bart Henderson, James Gourley, Adam Miller and Ed Hibbard for the herds of
Buffalo prevalent on the plateau.[5] The plateau is traversed by the Buffalo Plateau trail on the west and the Buffalo Fork Trail on the east.[6]
The Madison Plateau, the largest of the named plateaus, lies south of the
Madison River and west of the
Upper and
Lower Geyser Basins. It extends south from the Madison River to the Continental Divide and west to the park border. The Plateau is virtually inaccessible because only one trail, the Summit Lake Trail, traverses the plateau east to west. The Fairy Creek Trail penetrates the eastern edge of the plateau on its way to
Fairy Falls and Little Firehole Meadows.[9]
The Mirror Plateau is a remote plateau west of the upper
Lamar River and is in the headwaters of
Pelican Creek which flows into
Yellowstone Lake. The Plateau takes its name from Mirror Lake, originally named Divide Lake because it separates the Lamar and Pelican Creek drainages. During the 1878 Geological Survey,
Ferdinand V. Hayden named this lake—Mirror Lake for its propensity to mirror or reflect the surrounding terrain.[11]
The Pitchstone Plateau, named after the lava
pitchstone, occupies the southwest corner of the park in the
Bechler and
Fall River drainages. The
rhyolite lava flows that created the plateau occurred about 70,000 years ago.
Solfatara is a small plateau in the headwaters of the
Gibbon River. It lies just west of Canyon and south of
Grebe Lake. It was named in 1883 by geologist Walter Weed for a
solfatara, a thermal vent that emits hydrogen sulfide, steam and other gases.[14] The Plateau is bounded by the Norris-Canyon road on the south and Wolf Lake-Cascade Lake trails on the north. The Grebe Lake trail crosses the center of the plateau.[15]
Trident is a small, remote plateau in the southeast corner of park in the headwaters of the
Yellowstone River east of
The Trident. It extends east into the
Teton National Forest in Wyoming. The Trident was named by geologist
Arnold Hague in 1885 because it resembled a three pronged
Trident.[17]
