ABSTRACT - EXPLORING THE BOHEMIA MINING DISTRICT OF OREGON

This book is designed as a reference atlas and provides an historical look into the discovery of gold in the Western Oregon Cascades beginning in 1858 in the region known today as the Bohemia Mining District. The area is high with ridge-lines and peaks over 5,000-feet and steep rocky slopes making travel back then nearly unbearable and even today very difficult. It begins with the earliest prospectors who followed the Native American trails into the heart of the Calapooya Mountains searching for a glimmer of yellow in the creeks. The surveying of mining claims started here even before the Public Land Survey System subdivision of townships had begun. This book spans nearly 150-years and pulls together important geodetic and cadastral survey work in the form of mineral survey plats, mine maps, photos, and little-known facts forming an historical chronological record.

DEDICATION – TO THE EARLY U.S. DEPUTY MINERAL SURVEYORS

This book is dedicated to the early U.S. Deputy Mineral Surveyors who worked under the U.S. General Land Office (GLO) in the Bohemia Mining District between 1890 and 1946. This atlas also includes mineral survey maps and records from 1946 toward the present performed under the jurisdiction of the Bureau of Land Management (BLM). Even though they are long gone, their dedicated survey work remains on the ground, in their field notes and survey plats.  Follow their footsteps and appreciate their dedication and perseverance as they survey and map the mining claims of Bohemia.
