See the tree canopy in RoamWhich sites at Signal Mountain Campground get the most sun?
Only a few. 8 of 78 sites are truly sunny and 15 more get some sun; the rest are shaded.
See the tree canopy in RoamWill Starlink work at Signal Mountain Campground?
At some sites. About 28 of 78 sites have a clear gap in the trees for Starlink and 26 a partial one; the rest sit under trees. 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.

1 of 78 sites is flat, and 15 more have a gentle slope most RVs can level with blocks; 62 are steeper, better for tents. Sites that take RVs or trailers fit rigs up to 30 ft.

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.
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. Photos: Recreation.gov.
From the campground’s Recreation.gov listing: “The campground offers tent camping and pull-in/back-in sites for RVs or trailers up to 30 feet. This campground offers 24 sites with 30 and 50-amp hookups which are popular during the early and late season. The campground is organized in three loops, with the first loop offering both electric and non-electric generator sites, the second loop offering non-electric generator sites, and the third loop being non-electric and generator free . Tent pads are available at select sites and all sites have picnic tables, fire rings and bear-proof food storage boxes. Parking pads and areas for tents can vary greatly in size and care should be given when selecting a site. The Signal Mountain Campground sits slightly elevated from Jackson Lake in a predominantly lodgepole pine forest, which continues up Signal Mountain to the east. Signal Mountain itself is an isolated glacial moraine which rises over 800ft and offers sweeping views of the Jackson Hole valley. The campground is located directly across the lake waters from Mt. Moran, the park’s second tallest peak.”
