Three chapters. None of them a footnote.
The 1807 traverse is usually told as a "first non-Native description of Yellowstone" story. That's one chapter. The country Colter walked carried two longer ones — a fur-trade economy that paid for everything he did, and Indigenous homelands he was walking through, not into.
Indigenous homeland
Crow (Apsáalooke) east of the Absarokas. Eastern Shoshone and Bannock in the Wind River, Jackson Hole, and Pierre's Hole. Blackfeet (Niitsitapi) to the north. None of the country Colter walked was empty.
The 1807-08 traverse was a winter trade mission into known Indigenous geography, conducted with Crow guides for at least part of the loop. The 1808 escape from Blackfeet warriors near Three Forks — Colter's Run — is the most-told single anecdote about him. It needs careful telling: the Blackfeet were defending homeland during a generational conflict that began with the Two Medicine killing on Lewis & Clark's 1806 return.
Crow / Eastern Shoshone / Blackfeet Tribal Historic Preservation Office consultation before publish — not after.
Manuel Lisa's economy
Lisa's Fort Raymond, built November 1807 at the Bighorn-Yellowstone confluence, was the first American trading post in the Rocky Mountains. Colter was sent west because that's what Lisa was paying him to do. His 1808 trip (the famous Run) was a trade expedition with John Potts — not exploration.
Colter dies in 1812 or 1813 in Missouri, just a few years after walking back from the Tetons. The fur-trade economy that paid for the whole story is the connective tissue of the route. The Museum of the Mountain Man in Pinedale is the primary interpretive institution for the chapter.
Lisa's Fort. Pinedale. Three Forks. Colter's death in St. Louis. The fur-trade economic geography that frames every choice he made.
"Colter's Hell" and the rest
Colter is credited as the first non-Native to describe what is now Yellowstone and Grand Teton. The credit is real. The framing matters.
"Colter's Hell" is the cleanest example. Per USGS — the sulfur springs and fumaroles he described to Clark were on the Shoshone River west of present-day Cody. Not the Yellowstone geyser basins. Nineteenth-century writers conflated the two; the "Colter discovered the geysers" story is a later invention. The map calls this out where it sits.
The Colter Stone — found 1931 outside Tetonia, ID; inscribed "John Colter / 1808"; on loan to the Teton Valley Historical Museum — is a public-curiosity hero pin, not evidence. The map treats it that way.
What this means for the build
Practically, this changes a few things about how coltertrace.org gets built — versus a simpler "drive the route" tourism product:
- Confidence is rendered on the map. Jacob's
Confidencefield (High / Medium / Low) drives line opacity. Low-confidence segments visibly read as speculative. - Crow / Shoshone / Blackfeet consultation precedes publish. Lisa's Fort, Colter's Run, and Pierre's Hole each carry a tribal-homeland chapter; copy is co-authored, not written for them.
- "Colter's Hell" gets a hero site that names the conflation. The USGS-confirmed geography is the lead, not the romanticized version.
- Highway numbers are in the typography. Jim Mallory's specific ask. US-89/191/287, US-14/16/20, WY-296, US-212, Teton Pass — visible on the auto-route layer at every zoom.
