The site of modern-day Winnemucca has been important to Nevada since the first explorers traversed the region in the late 1820s. It later became a critical place for early settlers, and marked the point at which the immigrant trail headed south toward the Sierra Nevada passes. Winnemucca became a major distribution point for the Central Pacific Railroad, established itself as the center of commerce in north-central Nevada, and was the site of a major bank robbery that remains controversial to this day.
