About this map

Initial Point stands as the primary geographic anchor for this 1890s survey, marking the origin for all public land surveys in Idaho. The landscape is defined by the deep canyon of the Snake River as it carves through the basalt-capped plains between Ada and Owyhee counties. Transportation in the northern portion of the quadrangle is dictated by the Oregon Short Line Railroad, which links early trackside stops like Kuna, Mora, and Bisuka.

South of the river, the terrain shifts toward the volcanic formations of Sinker Butte and Basalt Butte, leading toward the small settlement of Oreana along Castle Creek. This reconnaissance-style mapping illustrates the early development of the region before extensive irrigation, showcasing a network of seasonal watercourses like Ten Mile Creek and Indian Creek that influenced the placement of original homesteads and rail sidings.
