This entrance was sent in by Iris Nelson. It's an entrance in the picturesque city of Bisbee, AZ. Bisbee was founded in 1880 and named after Judge DeWitt Bisbee, a financial backer of the Copper Queen Mine. This mining camp proved to be one of the richest mineral sites in the world, producing nearly three million ounces of gold and more than eight billion pounds of copper, not to mention the silver, lead and zinc that came from these rich Mule Mountains. By the early 1900s, the Bisbee community was the largest city between St. Louis and San Francisco. When mining became unprofitable in the 70s the city slowly evolved into an attractive artist colony and retirement community emphasizing monthly special events and tourism.
