Deep Notch is a mountain pass in Greene County, New York at about 585 m (1,919 ft) above sea level. The nearest town is Woodstock, about 29 km (18 mi) away (Deep Notch lies NW of town).
Deep Notch, sometimes West Kill Notch, or Echo Notch, is a mountain pass in Lexington, New York, United States. It divides two Catskill peaks, both subpeaks of high peaks of the range. The narrow groove between the steep, high slopes on either side is traversed by state highway NY 42 and the Shandaken Tunnel, part of the New York City water supply system. It has been called "striking" and "a marvel of grandeur and beauty". The rocky slopes have required extra fencing at the base to prevent slides from blocking the road, the only paved road from northwestern Ulster County to neighboring towns in Greene County. Their steepness has also made them attractive to ice climbers, a recreational opportunity not widely available elsewhere in the Catskills.From the Wikipedia article “Deep Notch”, licensed under CC BY-SA 4.0.

Azimuth is measured clockwise from true north (90° = east, 270° = west). Computed for 2026; values change by less than a degree from year to year.
Golden hour & blue hour by month
Mountain passes sit above valleys, so they reward sunrise and sunset with layered ridges, valley fog and long shadows.

Local time (America/New York), 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 Deep Notch, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.2 hours on a moonless night), and the core peaks around 19° above the southern horizon. Our light-pollution model puts the sky at about Bortle 4 (rural / suburban transition), good enough for detailed Milky Way images.

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: 4 Bortle 4 — Rural / suburban transition. Light domes are visible in several directions; the Milky Way is clear but lacks detail near the horizon. Modeled zenith brightness ≈ 21.01 mag/arcsec². Aurora needs roughly Kp 5.5+ 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 53% average cloud cover) and December as the cloudiest (78%). 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 mountain pass
- Summit pull-outs often face one direction; use the sun azimuth table to see whether sunrise or sunset suits the view.
- Wildflowers bloom late at pass elevations — often July to early August in the Rockies and Sierra.
- Check road status before driving: many high passes close seasonally or after storms.
- Look for the road itself as a leading line — switchbacks from above make strong compositions.
- Weather changes fast at elevation; carry layers even in summer.
- Bring a spare battery — cold weather and long exposures drain them fast.
Season: Summer and early autumn are the main season; winter visits depend on plowing and avalanche conditions.
Suggested gear: Telephoto lens, Tripod, Warm layers, Road-condition app. Work out exposures with the depth of field, ND filter and NPF rule calculators.
