Coconino National Forest
Of the more than 600 volcanoes that define northern Arizona’s landscape, only one offers an opportunity for hikers to walk into the innards of a dormant mountain of fire. For reasons not entirely understood by geologists, the northeastern flank of Red Mountain collapsed, exposing the intricate internal structure of the 740,000-year-old cinder cone. Tiny cinders crunch underfoot along the ponderosa-shaded trail that leads into a visually striking arena of towering stone pillars and contorted lava formations. A secured six-foot ladder must be climbed in order to get into the most spectacular part of the mountain where disintegrating layers of red, ocher and black cinders create a maze of clefts and canyons and to explore.
