Photographs

4,583 of 7,082 campgrounds carry a photograph. The managing agency took it and supplies it through Recreation.gov: the National Park Service, the Forest Service, the Bureau of Land Management and others. Works of the United States government sit in the public domain, and every page names the agency whose photograph it shows.

No campground here is shown by a generated image. If a campground has no agency photograph, its page shows none rather than an illustration of somewhere that looks plausible. Generated artwork is decoration, attached to no facility. The picture at the top of the home page is one, and its alt text says so; where an illustration carries an article instead, the caption under it opens with the word Illustration and the article keeps the prompt and the seed that made it.

Pictures on the notes

Every article carries one. Where a photograph exists under a licence allowing commercial use and modification, the article uses it, credits the author and links the file it came from. Where none does, we generate the picture locally and label it as an illustration on the article itself. Every file lives in this site and loads from nowhere else, so reading an article tells no third party that you read it.

2 of them carry a share-alike licence. We crop and re-encode, which makes our versions adaptations, so we offer them under the same licence as the originals.

Everything else

This domain serves the typefaces rather than a font service, so no third party learns what you are reading. The site loads no icon library, and it runs no analytics beyond what Privacydescribes.

The site is built with Next.js and React, and every page is rendered on the server — the HTML that arrives already contains the answer. Script runs afterwards for a handful of controls, the length slider and the filters among them. It loads from this domain and talks to nothing else.

With thanks

To the agency staff who measured several tens of thousands of driveways and wrote the numbers down. This site rearranges their work and adds nothing to it.
