Cook Forest State Park — a state park in Jefferson County, Pennsylvania — is a rewarding subject for landscape photographers. It sits roughly 16.5 km (10.3 mi) SSW of Marienville.
Cook Forest State Park is a 8,500-acre (3,440 ha) Pennsylvania state park in Farmington Township, Clarion County, Barnett Township, Forest County and Barnett Township, Jefferson County, Pennsylvania in the United States. Located just south of the Allegheny National Forest, the park is a heavily wooded area of rolling hills and mountains along the Clarion River in northwestern Pennsylvania. Cook Forest State Park is known for some of America's finest virgin white pine and hemlock timber stands and was once called the "Black Forest" due to the preponderance of evergreen tree coverage. Cook Forest is now a National Natural Landmark and was rated one of America's top 50 state parks by National Geographic Traveler magazine. It was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) and its Bureau of Parks as one of "25 Must-See Pennsylvania State Parks".From the Wikipedia article “Cook Forest State Park”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
State parks often protect a signature feature — a gorge, lake or overlook — that is best in early morning before visitors and harsh light arrive.

Milky Way & night sky
From Cook Forest State Park, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 4.5 hours on a moonless night), and the core peaks around 20° above the southern horizon. Our light-pollution model puts the sky at about Bortle 3 (rural sky), 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: 3 Bortle 3 — Rural sky. Some light domes sit on the horizon, but the Milky Way still looks complex overhead. Modeled zenith brightness ≈ 21.61 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 September as the clearest month (about 55% average cloud cover) and December as the cloudiest (84%). July is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.
