See the tree canopy in RoamWhich sites at Ray Behrens Campground get the most sun?

At some sites. About 43 of 165 sites have a clear gap in the trees for Starlink and 36 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.
See the tree canopy in RoamWhich sites at Ray Behrens Campground are the most level?
26 of 165 sites are flat, and 62 more have a gentle slope most RVs can level with blocks; 77 are steeper, better for tents. Sites that take RVs or trailers fit rigs up to 80 ft.

Mostly. T-Mobile and Verizon report coverage at every site; AT&T at 147 of 165. 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. Photos: Recreation.gov.
From the campground’s Recreation.gov listing: “Ray Behrens Campground has three loops: Deer Run, Little Bluestem and Cedar Ridge. All campsites come with electric hookups. Showers and accessible flush toilets are in close proximity of every site. The park also features a marina and playgrounds. The Salt River flows through rolling hills of north-central Missouri, where it is dammed to form the 18,000-acre Mark Twain Lake. A variety of recreation areas surround the lake, including the Mark Twain State Park.”
