Leslie Gulch is a canyon in Malheur County, Oregon, United States. It is on the east side of Owyhee Lake, a reservoir on the Owyhee River. Its abundant and striking rock formations are made of tuff. The gulch was named after a local rancher, Hiram E. Leslie, who was hit by lightning here in 1882. Previously it had been called "Dugout Gulch."From the Wikipedia article “Leslie Gulch”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Canyons need light from above: rims glow at sunrise and sunset, while deep or narrow sections are brightest near midday when reflected light bounces off the walls.

Milky Way & night sky
From Leslie Gulch, 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 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 ≈ 21.84 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 27% average cloud cover) and December as the cloudiest (73%). 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 canyon
- A long lens on a tripod handles the low light inside canyons better than raising ISO.
- From the rim, sunrise and sunset side-light reveals layers; a telephoto picks out buttes and shadows.
- In narrow canyons, reflected light creates orange and purple glows; avoid including bright sky in the frame.
- Check flash flood forecasts before entering slot or narrow canyons — rain miles away can flood them.
- Shoot RAW to keep the most latitude for high-contrast sunrise and sunset scenes.
Season: Spring and autumn are comfortable; summer monsoon storms bring dramatic skies but higher flood risk in the Southwest.
Suggested gear: Tripod, Wide and telephoto lenses, Lens blower, Weather radio or app. Work out exposures with the depth of field, ND filter and NPF rule calculators.
