Fumarole Butte is a volcano in Millard County, Utah. It sits roughly 34 km (21 mi) NNW of Delta.
Fumarole Butte is a shield volcano in central Juab County, Utah, United States. Built during the Quaternary period, it is composed of basaltic andesite. It stands 207 meters (679 ft) in height and has a diameter of 12 kilometers (7 mi). Under the volcano lies Crater Bench, the result of an eruption of basaltic andesite. To the east of the volcano are a series of hot springs, known as Baker Hot Springs.From the Wikipedia article “Fumarole Butte”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Volcanic cones and lava fields have strong shapes that read well in side-light; dark basalt needs careful exposure.

Milky Way & night sky
From Fumarole Butte, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.0 hours on a moonless night), and the core peaks around 22° above the southern horizon. Our light-pollution model puts the sky at about Bortle 2 (typical truly dark 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: 2 Bortle 2 — Typical truly dark site. The summer Milky Way shows rich structure; clouds look like black holes in the stars. Modeled zenith brightness ≈ 21.82 mag/arcsec². Aurora needs roughly Kp 8.0+ to show low on the northern horizon here.
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 30% average cloud cover) and December as the cloudiest (68%). 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 volcano
- Long lenses from 20–60 miles away make large stratovolcanoes dominate the horizon.
- Check local volcanic activity notices and area closures before visiting.
- Snow-capped volcanoes reflect alpenglow at sunrise — shoot from a lake or meadow for a reflection.
- Lava rock is sharp and unstable; stay on trails.
- Tell someone where you're going in remote areas and carry the ten essentials.
