See the tree canopy in RoamWill Starlink work at Cottonwood Point Campground?
Easy here. About 136 of 166 sites have open sky for a Starlink dish, and 16 more have a partial gap. 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.

39 of 166 sites are flat, and 75 more have a gentle slope most RVs can level with blocks; 52 are steeper, better for tents. Sites that take RVs or trailers fit rigs up to 70 ft.

Yes. T-Mobile, Verizon and AT&T all report coverage at every site at Cottonwood Point Campground. 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.
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 offers 164 individual sites, along with two group camping areas and two group day use picnic shelters. Campsites offer plenty of shade and include picnic areas with grills and tables. Electrical pedestals are either 50 or 30 amp. Every 50 amp pedestal has 50/30/20 outlets available. All 30 amp pedestals have 30/20 outlets available. The 20 amp outlets are typical residential 110 Volt wall outlets. Additionally you will find two boat ramps between sites 62 and 67. Completed in 1968, Marion Reservoir encompasses 6,200 acres of water surrounded by 6,000 acres of public lands. The surrounding expanse of forest provides visitors with endless recreational activities, set against the backdrop of the sparkling lake.”
