Thunderbolt Peak is a mountain peak in Fresno County, California at about 4,247 m (13,934 ft) above sea level. It is part of Kings Canyon National Park. It sits roughly 22 km (13 mi) WSW of Big Pine.
Thunderbolt Peak is a peak in the Palisades group located in the Sierra Nevada of California. It rises to 14,009 feet (4,270 m) and could be considered the thirteenth-highest peak in the state, but since the peak has less than 300 feet (91 m) of prominence it is usually considered a subsidiary peak of North Palisade. But if it is considered a separate mountain peak, Thunderbolt Peak is the northernmost fourteener in the Sierra Nevada. The first ascent was attempted by a party of very well-known climbers. During the climb, a lightning bolt struck very close to Jules Eichorn, breaking his concentration. The mountain was named in commemoration of this event.From the Wikipedia article “Thunderbolt Peak”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Summits catch first and last light — alpenglow can turn rock pink or orange minutes before sunrise and after sunset while valleys stay in shadow.

Milky Way & night sky
From Thunderbolt Peak, the Milky Way core is visible in a dark sky from March through October. June gives the longest window (about 5.5 hours on a moonless night), and the core peaks around 24° 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 ≈ 21.81 mag/arcsec².
Weather & best season
Long-term NASA satellite data for this area show September as the clearest month (about 21% average cloud cover) and December as the cloudiest (54%). 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 peak
- Afternoon thunderstorms are common in summer at high elevations — plan summit hikes for early morning.
- Snow on the summit holds detail best when you expose for the highlights and lift shadows later.
- Alpenglow lasts only a few minutes; set up and focus beforehand.
- Clouds around the summit add drama — a clear blue sky is often the least interesting condition.
- Scout in daylight if you plan to shoot at night or before sunrise.
Season: Early summer keeps snow on the peaks with green valleys below; autumn adds aspen or larch color in many ranges.
Suggested gear: Telephoto lens, Lightweight tripod, Warm layers, Microspikes in shoulder seasons. Work out exposures with the depth of field, ND filter and NPF rule calculators.
