Griswold Lake is a lake in Elko County, Nevada at about 2,811 m (9,222 ft) above sea level. It sits roughly 13.2 km (8.2 mi) SE of Spring Creek.
Griswold Lake is a glacial tarn in the Ruby Mountains of Elko County, Nevada, United States. It is within the Ruby Mountains Ranger District of the Humboldt-Toiyabe National Forest. The lake is located at the head of Hennen Canyon, at approximately 40°38.1′N 115°29.2′W, and at an elevation of 9,222 feet (2,811 meters). It has an area of approximately 17 acres (6.9 hectares), and a depth of up to 20 feet (6.1 meters). Griswold Lake is the principal source of Butterfield Creek, which flows down Hennen Canyon before exiting the mountains into Pleasant Valley. The lake is named after Chauncy "Chan" Griswold, an early rancher in Pleasant Valley and the father of Nevada Governor Morley Griswold. Butterfield Creek was also named after an early rancher, Henry Butterfield.From the Wikipedia article “Griswold Lake (Nevada)”, licensed under CC BY-SA 4.0.

Milky Way & night sky
From Griswold Lake, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.7 hours on a moonless night), and the core peaks around 20° 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 ≈ 21.72 mag/arcsec². Aurora needs roughly Kp 7.5+ 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 31% average cloud cover) and December as the cloudiest (69%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this lake
- Mist often lifts off lakes on cold mornings after warm days, especially in autumn.
- Include shoreline rocks, reeds or a log as foreground to give the reflection depth.
- Expose for the brighter sky; reflections are typically half a stop to a stop darker.
- After sunset, long exposures smooth wind ripples into glass.
- Check road and trail conditions with the managing agency before you go.
Season: Autumn mornings bring mist and fall color; high-elevation lakes are usually ice-free only from early summer to mid-autumn.
Suggested gear: Tripod, Circular polarizer, Wide-angle lens, Waterproof boots. Work out exposures with the depth of field, ND filter and NPF rule calculators.
