Map of the Yellowstone National Park (Norris, 1881)

P. W. Norris’s map of Yellowstone National Park for his annual report as its superintendent, signed at the Mammoth Hot Springs headquarters in November 1881 and compiled from his own explorations and other sources, chiefly Hayden’s survey of 1878: the park’s roads, bridle trails and hotel sites, the geyser and hot-spring basins tinted red, Norris’s numbered camps and his routes of 1880 and 1881, and the Crow Indian Reservation beyond its northern line. It letters the “Bannack Trail” — the road the Bannock and their Shoshone neighbours took across the Yellowstone country to the buffalo plains east of the mountains — from below Bell’s Peak in the Gallatin Range, past a small lake and down Indian Creek to Gardiner’s River, and marks an “Indian Camp” below Hoodoo (Goblin) Mountain and “Indian Pond and Camp” on Mary Bay of Yellowstone Lake. The Sheepeater Cliffs on Gardiner’s River carry the name of the Tukudeka (Sheep Eaters), the Shoshone people who lived in these mountains year round. Not shown: the title and the table of distances and hotel sites below the map.

AccuracyAbout 4 km (RMS 1.3 km at 60 control points). Placed by hand in a map-queue session and approved by a person. If something sits in the wrong place, members can fix it with Fix placement on the map.
MethodPlaced by hand on the map’s own graticule: an affine fit to 60 points — 23 crossings of its 10′ meridians and parallels read off the scan, which the fit holds to within 0.6 km, and 37 places drawn on it (peaks, lakes and islands, falls, geyser basins, river mouths and the Clark’s Fork mines at Cooke City), 20 of them within 1 km of where it puts them and 30 within 2 km. Farther off: the Absaroka peaks east of the park, sketched outside the surveyed ground (Index Peak and Pilot Knob 3.5–4 km, Hoodoo Mountain 2.5 km), Peale’s Island in the South Arm of Yellowstone Lake and Riddle Lake (3.5 km), and Tower Falls (2.5 km).
