Questions
Which sites at Acorn Campground are the shadiest?
About 50% of them. 69 of 126 sites have good shade and 57 are mostly open.
See the tree canopy in RoamWhich sites at Acorn Campground get the most sun?
Some. 36 of 126 sites are open to the southern sky, good for solar panels, and 40 more get some sun.
See the tree canopy in RoamWill Starlink work at Acorn Campground?
Easy here. About 109 of 126 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.
See the tree canopy in RoamWhich sites at Acorn Campground are the most level?
4 of 126 sites are flat, and 18 more have a gentle slope most RVs can level with blocks; 104 are steeper, better for tents. Sites that take RVs or trailers fit rigs up to 36 ft.

Mostly. T-Mobile and Verizon report coverage at every site; AT&T at 98 of 126. 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: “Acorn Campground offers 128 spacious campsites with modern amenities such showers and accessible flush toilets, as well as drinking water, an important part of staying hydrated in the summer sun. The 4,400 surface-acre lake was created in 1964 with the completion of New Hogan Dam. When full, the lake has 50 miles of shoreline and extends nearly eight miles upstream to the confluence of the north and south forks of the Calaveras River. The dam was built to provide flood protection to the city of Stockton and water for irrigation, drinking and hydroelectric power, and it now offers recreation opportunities for thousands of visitors each year.”
