Rio Colorado of the West, explored by 1st Lieut. Joseph C. Ives, Topl. Engrs., under the direction of the Office of Explorations and…
Lieutenant Joseph C. Ives’s map of his 1857–58 expedition up the Colorado River and east across the plateau to the Hopi mesas, Fort Defiance and Zuni, drawn by F. W. von Egloffstein. It names the Hopi villages one by one — Orayba (Oraibi), Shung-o-pah-wee (Shungopavi), Sha-pau-lah-wee (Shipaulovi), Moo-sha-neh (Mishongnovi), Hual-pee (Walpi), See-cho-mah-wee (Sichomovi) and the Tegua town (Hano) — with Zuni and the country of the Navajo, Hualapai, Havasupai (“Cosninas”), Southern Paiute (“Pah Utahs”) and Tonto, and marks two “Ind. trail” lines crossing its route east of the mesas, between Peach Orchard Spring and Pueblo Colorado Wash.

| Accuracy | About 12 km (RMS 1.2 km at 46 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. The graticule itself fits to about 2 km, but Egloffstein drew some features well off it: the five anchors sit 2–7 km from their graticule positions, and away from them a feature can be about 12 km out (Bill Williams Mountain is). |
| Method | Placed by hand: a smoothing thin-plate spline through the sheet’s own graticule (crossings every degree of longitude and half degree of latitude, from a polyconic fit to 54 points read off its meridians and parallels, 0.1 km RMS) and five places the map draws 2–7 km from where its graticule puts them — Zuni, Oraibi, Walpi, Fort Defiance and the mouth of Diamond Creek; 46 points in all. See the methodology. |
