Anemone Geyser

Chinese Spring (formerly called Chinaman Spring) is a hot spring in Yellowstone National Park, Teton County, Wyoming, in the United States.Chinese Spring was named for a Chinese immigrant who often washed laundry in the spring in the 1850s.

Beehive Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States. The 4-foot (1.2 m) tall cone resembles a straw beehive. Beehive's Indicator is a small, jagged cone-type geyser located about 10 feet (3.0 m) from Beehive.

Doublet Pool is a hot spring in the Upper Geyser Basin of Yellowstone National Park, Wyoming. Doublet Pool is 8 feet (2.4 m) deep and its temperature is approximately 194.4 °F (90.2 °C). Its scalloped edge is made of geyserite. Eruptions can occur in Doublet Pool, but only last up to 8 minutes. The pool on the right pulses over the vents about every two hours. Occasionally there will be vibrations, surface wave motion, and thumping; these effects are caused by collapsing gas and steam bubbles deep underground.

Aurum Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States, on Geyser Hill. Aurum can, at times, be very predictable. Other times it can be very erratic. Observations have led to the theory that Aurum's activity is linked to the meadow behind the geyser. When the meadow is wet, activity is regular with 3 to 4 hours between eruptions. When the meadow dries in late summer and early fall, the interval becomes less predictable ranging from 4 to 7 hours. Aurum also participates in the weekly Geyser Hill wave. It decreases and increases its interval at regular times during a week.Eruptions last about 90 seconds and range in height from 15 feet (4.6 m) to 25 feet (7.6 m). An eruption is usually preceded by bubbling in two small vents nearby. On rare occasions, an eruption will be followed by a second smaller eruption 5 to 10 minutes after the primary eruption.

Ear Spring is a hot spring in the Upper Geyser Basin of Yellowstone National Park in the United States. Located close to Old Faithful, on rare occasions Ear Spring will erupt as a geyser, and can shoot rocks and debris as well as water more than 25 feet (7.6 m) for a few minutes. On September 15, 2018, Ear Spring was seen on the National Park Service webcam at Old Faithful erupting for a minute and reached heights of 20 to 30 ft (6.1 to 9.1 m). This was the largest eruption the pool may have had since 1957. The eruption tossed small rocks out and the heated water killed the surrounding bacterial mats that normally thrive in less heated conditions. Likely related to the eruption of Ear Spring, a new thermal feature opened up under the pedestrian boardwalk near Pump Geyser which resulted in the National Park Service temporarily closing off the boardwalk. This new thermal feature was spouting water the night of September 18-19, 2018. Additionally, Doublet Pool and North Goggles Geyser have both been more active in the period immediately after the rare eruption of Ear Spring.

Old Faithful is a cone geyser in Yellowstone National Park in Wyoming, United States. It was named in 1870 during the Washburn–Langford–Doane Expedition and was the first geyser in the park to be named. It is a highly predictable geothermal feature and has erupted every 44 minutes to two hours since 2000. The geyser and the nearby Old Faithful Inn are part of the Old Faithful Historic District.

Big Cub Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States. Big Cub is part of the Lion's Group of geysers, a cluster of geysers that all share an underground connection. The other geysers in this group are Lion Geyser, Lioness Geyser, and Little Cub Geyser.

The Old Faithful Inn is a hotel located in Yellowstone National Park, Wyoming, United States, with a view of the Old Faithful Geyser. The Inn has a multi-story log lobby, flanked by long frame wings containing guest rooms. With its log and limb lobby and massive (500-short-ton or 450-metric-ton, 85-foot or 26-meter) stone fireplace, the inn is an example of the "Golden Age" of rustic resort architecture, a style which is also known as National Park Service Rustic. It is one of the few log hotels still standing in the United States, and was the first of the great park lodges of the American west. Initial construction was carried out over the winter of 1903–1904, largely using locally obtained materials including lodgepole pine and rhyolite stone. When the Old Faithful Inn first opened in the spring of 1904, it boasted electric lights and steam heat. The structure is the largest log hotel in the world; possibly even the largest log building in the world. In 2007 the American Institute of Architects conducted a survey to determine the 150 favorite buildings in America; the Old Faithful Inn ranked 36. The Inn, which was designated a National Historic Landmark in 1987, is itself part of the Old Faithful Historic District. Old Faithful Inn is a member of Historic Hotels of America, the official program of the National Trust for Historic Preservation.

The Old Faithful Museum of Thermal Activity was one of a series of four "trailside" museums built in Yellowstone National Park in 1929. Funded by a grant of $118,000 from Laura Spelman Rockefeller, the museums interpreted park features for visitors, and represented an early version of the visitor information center concept that became widespread throughout the National Park Service. The four museums were notable examples of the National Park Service Rustic style, and all were designed by Park Service architect Herbert Maier. The surviving Norris Museum, Fishing Bridge Museum and the Madison Museum are collectively listed as National Historic Landmarks.The Old Faithful museum, the first of the series, was built at a cost of $8,500 and was completed in 1929. The museum was a low T-shaped single-story structure of rustic log and stone construction. Two stepped sections of roof dominated the main portion of the building with deep overhangs supported by angled log brackets resting on a raised stone foundation sill. A perpendicular wing extended in the direction of the parking lot. The building resembled the Madison and Fishing Bridge museums. The museum's surroundings featured an amphitheater for ranger talks and a small garden of native botanical specimens.The Old Faithful museum was demolished in 1971 to make way for a full-scale Mission 66 visitor center on the site, midway between the Old Faithful Inn and the Old Faithful Lodge, facing Old Faithful geyser. This visitor center was in turn demolished in 2006 and was replaced by the Old Faithful Visitor Education Center, opened in August 2010.

Old Faithful Lodge in Yellowstone National Park is located opposite the more famous Old Faithful Inn, facing Old Faithful geyser. The Lodge was built as a series of detached buildings through 1923 and was consolidated into one complex by architect Gilbert Stanley Underwood in 1926-27. The Lodge is included in the Old Faithful Historic District.Compared with the Inn, which is a full-service hotel, the Lodge provides only dining, social, administrative and registration services for lodgers, who are accommodated in detached cabins surrounding the Lodge. Several earlier buildings were consolidated by Underwood into the single rambling structure, with the help of National Park Service architect Daniel Ray Hull, in 1926-27. The Lodge includes a common lobby, dining spaces and a recreation hall, known as Geyser Hall, of log construction in the National Park Service Rustic style. The roof structure of the 136-foot (41 m) by 100-foot (30 m) Geyser Hall is reminiscent of Gothic wood construction, with a height of 73 feet (22 m) to the ridge. The hall is arranged with a central nave-like structure, with subsidiary side aisles.Accommodations are located behind and to the east of the lodge in "frontier cabins" with en-suite toilets and "budget cabins" with communal toilets and showers. The lodge and cabins are open during the summer season. The cabins are descendants of the original tent camps established by the Shaw and Powell Camping Company in 1913-1915. From 1919 the camp was operated by several owners under the Yellowstone Park Camps Company. Concurrent with the construction of the consolidated Old Faithful Lodge, the camp was acquired by Harry W. Child in 1928 and renamed the Yellowstone Park Lodges & Camps Company. This company was amalgamated with Child's Yellowstone Park Company in 1936.

Hamilton's Stores were concessioners in Yellowstone National Park from 1915 to 2002. The stores were founded by Winnipeg native Charles Hamilton, who arrived in Yellowstone in 1905, aged 21, to work for the Yellowstone Park Association. The stores provided tourists with food, souvenirs, and sundries at the major attractions along Yellowstone's Grand Loop Road. Several buildings constructed for Hamilton are significant examples of the National Park Service Rustic style of architecture and have assumed prominence as attractions in their own right. Most are included as contributing structures in National Register of Historic Places historic districts.

Solitary Geyser is a fountain-type geyser in Yellowstone National Park, located above the Upper Geyser Basin. Eruptions last about a minute and are four to eight minutes apart; most eruptions are less than six feet (1.8 m) in height. It is very distinctive with clear blue water underneath and a base that is tinted orange. Solitary Geyser is accessible via the Observation Point loop trail behind Old Faithful. Originally this geyser was a hot spring known as Solitary Spring, which did not erupt. When water was diverted to a swimming pool, the water level was lowered sufficiently to cause eruptions. Since then the diversion of water has been stopped and the water has returned to its previous level, but eruptions continue.
