the pinnacles are chimneys formed when hot ash cooled after the massive eruption thousands of years ago.they are a colorful collection of 100-foot-tall spires, which are being eroded from the canyon wall. the spires are “fossil fumaroles,” each marking a site where volcanic gases rose through hot ash deposits, cementing the ash into more solid rock.
