1965 Map of Ophir B-2

About this map

The Innoko River meanders through this Interior Alaska landscape, defining a remote region of the Yukon-Koyukuk during the mid-1960s. Mining activity is anchored by the Esperanto Placer Mine situated near Esperanto Creek, a site of interest for those studying the history of gold extraction in the Innoko District. The terrain is characterized by prominent peaks like Madison Mtn and Caribou Mountain, which oversee a network of drainages including Mastodon Creek and Scandinavian Creek. Transportation through this often-frozen wilderness relied on seasonal routes, specifically a Winter Trail following the riverbanks and a Tractor Trail cutting through the northern uplands. The distribution of family or prospector-named features like Wilson Creek and Frisco Creek reflects the sparse but intentional footprint of early twentieth-century mining and exploration in the territory.
