Extensive lava fields dominate the western landscape of this 1948 survey, contrasting sharply with the intricate network of irrigation systems to the east. The Lava flows create a stark geologic boundary where the terrain remains largely undeveloped, while the fertile lands closer to the Snake River are crisscrossed by vital waterways like the Great Western Canal and Porter Canal. This distribution illustrates the historical reliance on engineered water management to sustain agriculture in the region.
