Mt Antero is one of only a handful of 14,000′ peaks that has a road that travels to within a short distance of the summit. The road up the mountain is rough and rocky, requiring four-wheel drive, topping out at 13,800′. From the end of the road at point 13,800 it’s a 1/2 mile and 470′ climb to the summit.
In 1881, a Salida man by the name of Nelson Wanemaker discovered gems high on Mt Antero. His discovery was publicized a few years later, and the mountain became a famous collecting area for aquamarine, phenacite, fluorite, topaz, and smoky quartz crystals. It has the highest concentration of minerals anywhere in the US. With findings far above timberline, this is the highest known gem locality in the United States.
