See the tree canopy in RoamWhich sites at Outflow Camping get the most sun?
Some. 40 of 75 sites are open to the southern sky, good for solar panels, and 13 more get some sun. These counts cover the 75 of 94 sites with a mapped location.

Easy here. About 68 of 75 sites have open sky for a Starlink dish, and 5 more have a partial gap. These counts cover the 75 of 94 sites with a mapped location. Satellite texting on a phone needs less open sky, but still works best from the most open spot you can find. This is our estimate from tree heights — check with the Starlink app's obstruction check when you arrive.

25 of 75 sites are flat, and 17 more have a gentle slope most RVs can level with blocks; 33 are steeper, better for tents. Sites that take RVs or trailers fit rigs up to 64 ft. These counts cover the 75 of 94 sites with a mapped location.

Mostly. Verizon and AT&T report coverage at every site; T-Mobile reports none. That's the coverage each carrier reports to the FCC, not a measured signal, so under trees or below a ridge it can be weaker.

How we know Sources and limits
Shade, sun and Starlink are our estimates from Meta and the World Resources Institute’s canopy-height model (about 2 m pixels, from satellite imagery calibrated with space lidar; CC BY 4.0). From 2 m above each site we trace 72 lines out to 60 m and note the tallest tree in each direction. Shade counts trees overhead, the canopy within 30 m and how much of the afternoon sky is blocked. Sun counts how open the southern sky is. Starlink needs open sky above 35°, with the northern half counted twice because US dishes tilt north, and we keep the best spot within 8 m of the site’s post. The model sees tree heights only, not trunks, buildings or hills, so check with the Starlink app when you arrive.
Slope is the ground at each site’s post over about 4 m, from USGS 3DEP 1 m lidar: level under 2%, gentle to 4% (most rigs level on blocks), sloped to 8% (fine for a tent), steep beyond.
Cell coverage is from the FCC Broadband Data Collection (carrier filings as downloaded May 2026): each site is tested against each carrier’s modelled outdoor 4G/5G coverage. It is what the carriers report, not a measured signal.
Fall color is the typical peak from NASA’s MODIS satellite record of when leaves change (2001–2023), limited to deciduous and mixed forest with USGS land cover (NLCD), calibrated to the USA National Phenology Network’s ground reports of colored leaves (CC BY 4.0). It is an average of many autumns, so the page gives a window, not a date.
Weather is NOAA’s 1991–2020 climate normals for the campground. Sites and facts are from Recreation.gov’s open data (July 2026). Map imagery: USGS The National Map.
From the campground’s Recreation.gov listing: “The campground contains a variety of sites, including walk-to group sites, RV sites and tent-only sites. Electric hookups are available in many sites. Flush toilets, showers, drinking water and a dump station are provided. The park also offers an amphitheater and children's playground. Hammock Stations have been added to the Bike and Hike and Group Camping sites. The country surrounding the lake is made up of narrow valleys and high rounded hills with steep slopes. Much of the land is covered with northern hardwoods including Beech, Sugar Maple, White Ash, Yellow Poplar and Basswood. A variety of wildlife makes its home around Youghiogheny River Lake, including deer, bear, turkey, grouse, rabbit and squirrel.”
