SLATE MOUNTAIN

SLATE MOUNTAIN
Coconino National Forest
Not actually made of slate, this hill is a laccolith, or a solidified heap of lava that pushed up the earth’s crust like a blister, but never broke the surface. Time has since eroded away the mountain’s top layers to expose the grayish-blue igneous rock called rhyolite, which early explorers mistook for “slate”. The moderate 5-mile round trip hike climbs 855 feet to the 8,215-foot summit.
