Located in Teton County, Wyoming, Fountain Geyser is a hot spring. It lies in or next to Yellowstone National Park, so park hours, fees and rules apply. The nearest town is West Yellowstone, about 26 km (16 mi) away (Fountain Geyser lies ESE of town).
Fountain Geyser is a geyser in the Lower Geyser Basin of Yellowstone National Park in the United States. Fountain is the dominant member of a group of geysers at the Fountain Paint Pots thermal area. Morning Geyser, which erupts from a vent close to Fountain's, is larger, but is inactive during most years. Fountain, by contrast, is usually active. It is a fountain-type geyser that erupts jets ranging in height up to 80 feet (24 m) or more, with most eruptions containing at least a few bursts that reach 40 to 50 feet. Intervals (= eruption start to eruption start) vary from year to year but are commonly about 4.5 to 6 hours, with occasional longer intervals of 11 to 12 hours. Durations of eruptions are typically about 30 minutes. Occasionally, Fountain departs from its usual behavior and enters so-called "wild-phase" eruption, during which the height is much reduced but the...From the Wikipedia article “Fountain Geyser”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Steam is most visible on cold mornings; backlight from a low sun makes rising steam glow.

Milky Way & night sky
From Fountain Geyser, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.5 hours on a moonless night), and the core peaks around 17° above the southern horizon. Our light-pollution model puts the sky at about Bortle 1 (excellent dark-sky site), which is excellent for astrophotography.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 1 Bortle 1 — Excellent dark-sky site. The Milky Way casts faint shadows; zodiacal light and airglow are obvious. Modeled zenith brightness ≈ 21.93 mag/arcsec². Aurora needs roughly Kp 5.5+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show July as the clearest month (about 39% average cloud cover) and February as the cloudiest (77%). July is the warmest month and December the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this hot spring
- A polarizer brings out the colors of mineral terraces and microbial mats.
- Respect bathers' privacy: ask before including people at soaking pools.
- Wind direction determines where steam drifts; shoot from the upwind side to see the pool.
- Condensation forms quickly on lenses; let gear acclimate and carry a cloth.
- Tell someone where you're going in remote areas and carry the ten essentials.
Season: Winter gives the most dramatic steam; some primitive springs are only accessible in summer.
Suggested gear: Circular polarizer, Lens cloth, Telephoto for distant pools. Work out exposures with the depth of field, ND filter and NPF rule calculators.
Permits, drones & access
National Park Service rules. Under federal law (54 U.S.C. 100905), still photography in National Park Service areas needs a permit only when it (1) takes place where members of the public are not allowed, (2) uses models, sets or props that are not part of the location's natural or cultural resources or administrative facilities, or (3) would cause the park to incur additional administrative costs to monitor the activity. Ordinary visitor and most landscape photography needs no permit. Commercial filming rules are separate and have changed in recent years — confirm current requirements with the park before a paid shoot.
Drones: Launching, landing or operating unmanned aircraft (drones) is prohibited in National Park Service units under a 2014 Superintendent's closure (36 CFR 1.5), except where a park has issued specific written approval. Flying from outside the boundary over park land can also violate park rules and disturb wildlife.
