Published in 1898 by the Press of The Owyhee Avalanche, this volume serves as both a foundational historical record and a practical commercial guide to Owyhee County, Idaho, during its late 19th-century resource boom. The text provides detailed accounts of the region's geography, emerging rail infrastructure, and lucrative mining operations, while also cataloging the local businesses, civic leaders, and pioneer residents who populated towns like Silver City, De Lamar, and Guffey. A keen insight drawn from the publication is how frontier newspapers actively functioned as regional boosters, utilizing these exhaustively detailed directories to legitimize rugged, isolated mining camps into permanent, investment-worthy municipalities by projecting a highly organized image of commerce and rapid modernization.
