County of gem

History & Founding

Located in west-central Idaho, this county’s history is intertwined with the region’s agricultural development and the influx of settlers drawn to its fertile lands. Established in 1891 from a portion of Payette County, its name is a playful nod to the area's rich deposits of semi-precious stones, particularly garnet and jasper. While not a major gemstone mining center, the presence of these minerals contributed to the county's identity. The early years were marked by the establishment of agricultural communities and the construction of irrigation systems crucial for farming in the arid climate. A fascinating anecdote from the early 1900s recounts a local farmer, convinced he’s discovered a massive diamond deposit, sparking a brief but enthusiastic “diamond rush” that ultimately proved fruitless, but further cemented the county’s connection to the idea of precious stones. The county played a vital role in Idaho’s agricultural expansion, contributing significantly to the state’s reputation as a leading producer of potatoes and other crops.

Geography & Landscape

The county’s geography is defined by its rolling hills and valleys, nestled within the foothills of the Rocky Mountains. It occupies a strategic location within the Snake River Plain, a vast, geologically significant basin. The Payette River, a major tributary of the Snake River, flows through the county, providing irrigation water and recreational opportunities. Elevations range from approximately 2,000 feet along the river to over 6,000 feet in the foothills. The climate is characterized by hot, dry summers and cold, snowy winters, typical of the Intermountain West. The landscape is a mix of agricultural fields, open grasslands, and forested slopes. Notable natural features include the expansive views of the surrounding mountains and the vibrant wildflowers that bloom in the spring.

Economy & Communities

The county’s economy is primarily driven by agriculture, with potatoes being the dominant crop. Emmett, the county seat, and Mountain Home are the two principal towns, each possessing a distinct character. Mountain Home, situated closer to the state’s central plateau, serves as a regional transportation hub. Emmett, on the other hand, retains a strong agricultural focus and a small-town charm. While agriculture remains the backbone of the economy, there's a growing presence of light industry and manufacturing, driven by the county’s strategic location and access to transportation routes. Major employers include agricultural processing facilities, retail businesses, and the U.S. Air Force’s Mountain Home Air Force Base, which significantly impacts the local economy. The area maintains a predominantly rural character, although the proximity to Boise contributes to some suburban influences.
