Otto Mears (May 3, 1840 – June 24, 1931) was a Colorado railroad builder and entrepreneur who played a major role in the early development of southwestern Colorado.[1][2]
Mears was known as the "Pathfinder of the San Juans" because of his road and railroad building projects through Colorado's San Juan Mountains in the late 19th century.[3] He built hundreds of miles of toll roads in the rough terrain of the young state of Colorado,[4] notably the Million Dollar Highway over Red Mountain Pass, connecting Silverton to Ouray.[5]
