Howser Spires (11,150 feet) reflect in a pretty tarn (mountain pond) in Bugaboo Provincial Park, south of Golden, British Columbia, Canada. The Bugaboos are a range in the Purcell Mountains, which are a subrange of the Columbia Mountains, which are west of the Rocky Mountain Trench. (Some USA maps label the “Percell Mountains” where their southern limit protrudes into the states of Idaho and Montana.) The igneous Bugaboo intrusion of 135 million years ago cooled into hard crystalline granite and was scraped into spires by glaciers eroding surrounding rock dating from 600 million to 1 billion years ago. Published in the Irish Mountain Log, "The magazine for Walkers and Climbers in Ireland", Summer 2008.
