1954 Map of Mount McKinley B-3

Resource extraction and early access routes are visible in the northeast corner within the Kantishna Hills. A Tractor Trail provides a historical record of overland transport through this interior terrain, leading toward the Antimony Mine near Eldorado Creek. Rising above the river valleys, landmarks like Brooker Mtn and the highland drainage of McLeod Lake provide essential navigation points for studying this era of the park's history before its later expansion.
