Hell Creek badlands, Garfield County

Garfield, Montana, United States

The Hell Creek badlands around Jordan, Montana, are the type area of the Hell Creek Formation and the world's most productive latest-Cretaceous dinosaur country, where the first Tyrannosaurus rex was found in 1902. Commercial Hell Creek material comes from private ranches, several of which run paid dig programmes; the checkerboard of BLM and refuge land means the same butte can be legal on one side of a fence and a felony on the other. Ask for the ranch and county before buying anything.

Rules

On BLM land, casual collecting of common invertebrate and plant fossils is allowed for personal use (reasonable amounts, hand tools, no sale); all vertebrate fossils, including teeth and bone fragments, require a BLM paleontological permit and remain federal property. Charles M. Russell NWR and Corps land around Fort Peck are closed to collecting. On private ranches, the landowner's written permission governs, and material may be sold. Record township, range and ranch on every specimen.
