The Quarry Exhibit Hall is a building constructed around a cliff face with about 1,500 dinosaur bones still embedded in it, left exactly where they were buried in a Jurassic river bar. You can put your hand on them. It is probably the single best place in the world to understand how a bone bed actually forms. LOOK ONLY, and the monument also protects Fremont petroglyphs.

This ground is protected. Photograph it, record it, leave it where it lies. On US federal land the Paleontological Resources Preservation Act 2009 makes collecting vertebrate fossils an offence, and penalties are real.
