About this map

The Initial Point stands as a primary landmark in this late 19th-century survey of southwestern Idaho, serving as the fundamental survey origin for the region's land divisions. The terrain is defined by the deep incision of the Snake River as it winds through the canyon lands, flanked by prominent volcanic features like Sinker Butte, Basalt Butte, and the Castle Buttes. Transportation and settlement are dictated by the presence of the Oregon Short Line Railroad, which parallels Indian Creek and connects the small railway stops of Kuna, Mora, and Bisuka.

South of the river in Owyhee territory, the landscape becomes increasingly dissected, with Castle Creek and the settlement of Oreana positioned near the rugged breaks. The scarcity of named features between the rail corridor and the river highlights the arid character of the Snake River Plain during this era of early territorial development, when water sources like Ten Mile Creek and scattered springs were vital for both the railroad and local ranching interests.
