Fossil Lake is a lake in Lake County, Oregon at about 1,309 m (4,295 ft) above sea level. The nearest town is Deschutes River Woods, about 102 km (63 mi) away (Fossil Lake lies SE of town).
Fossil Lake (designated by the Bureau of Land Management as Fossil Lake Area of Critical Environmental Concern) is a dry lakebed in the remote high desert country of northern Lake County in the U.S. state of Oregon. During the Pleistocene epoch, Fossil Lake and the surrounding basin were covered by an ancient lake. Numerous animals used the lake's resources. Over time, the remains of many of these animals became fossilized in the lake sediments. As a result, Fossil Lake has been an important site for fossil collection and scientific study for well over a century. Over the years, paleontologists have found the fossil remains of numerous mammals as well as bird and fish species there. Some of these fossils are 2 million years old.From the Wikipedia article “Fossil Lake (Oregon)”, 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.

Local time (America/Los Angeles), including daylight saving time. Golden hour runs from about −4° to +6° solar altitude, so the morning golden hour begins during blue hour, before sunrise.
Milky Way & night sky
From Fossil Lake, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 3.8 hours on a moonless night), and the core peaks around 18° 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 6.5+ 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 23% average cloud cover) and December as the cloudiest (73%). 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 lake
- After sunset, long exposures smooth wind ripples into glass.
- 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.
- 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.
