Phelps Lake is a lake in Teton County, Wyoming at about 2,023 m (6,637 ft) above sea level. It lies in or next to Grand Teton National Park, so park hours, fees and rules apply. The nearest town is Moose Wilson Road, about 13.7 km (8.5 mi) away (Phelps Lake lies NNE of town).
There are 44 named and countless unnamed lakes in Grand Teton National Park. The largest of these is Jackson Lake, a natural glacial lake that has been enlarged with the construction of the Jackson Lake Dam. The lakes range in size as well as ease of access. In addition to mountain tarns, there are several large peidmont lakes. Nearly all the lakes are glacial in origin, formed by glacial action that carved out the valleys and left moraine behind that acted as dams to lock in water. The lakes exist in the near pristine wilderness environment of the park, and recreational use, boating and fishing varies by lake. Elevation of the region classes these as alpine lakes, with Jackson lake being the largest alpine lake in the United States.From the Wikipedia article “Lakes of Grand Teton National Park”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Lakes reflect best in calm air — usually the first hour after sunrise, before breezes ripple the surface.

Milky Way & night sky
From Phelps Lake, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.7 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 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 ≈ 21.85 mag/arcsec². Aurora needs roughly Kp 6.0+ 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 38% average cloud cover) and December as the cloudiest (71%). 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
- For mirror reflections, get low and close to the water; the reflection grows with a lower camera.
- A polarizer can remove reflections to show the lakebed — or keep them, depending on rotation.
- 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.
- Scout in daylight if you plan to shoot at night or before sunrise.
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.
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.
