What’s in a Name?

A mining mogul, Robert "Old Mac" Mcintosh was admired throughout Routt County for his hospitality and kindness. While exloring the area near Encampment Mountain in North Routt, he noticed a diamond-shaped stand of evergreens in the middle of an open park. Diamond Park, he named it, would become a cherished place for locals to camp, horseback ride, mountain bike, or just enjoy some North Routt scenery without venturing too far from home.
