Map of Explorations in Alaska, 1899: All-American Route to the Yukon, from Tyoonok, Cook Inlet to Fort Gibbon, via the Upper Kuskokwim…
Lieutenant Joseph S. Herron’s 1899 map of his route from Tyonek on Cook Inlet over the Alaska Range and down the Kuskokwim to the Yukon, guided by Dena’ina and Upper Kuskokwim people: the Indian winter trails and summer trails he followed, the villages, and the Dena’ina and other names of the rivers and mountains.

| Accuracy | About 16 km (RMS 3.8 km at 9 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. |
| Method | Placed by hand on the sheet’s own graticule: its border ticks for 151°–155° W and 62°–65° N were fitted with a polyconic projection together with Fort Gibbon and Tyonek, the other coordinate of each tick taken from that fit, and the 9 points warped with a first-order (affine) polynomial. See the methodology. |
