tryfanとは 意味・読み方・使い方

Tryfan is a mountain in Snowdonia, Wales, forming part of the Glyderau group. It is one of the most recognisable peaks in the region, having a classic pointed shape with rugged crags. At 3,010 feet above sea level it is the fifteenth highest mountain in Wales. Between the mid-1980s and June 2010, its accepted height was 3,002 ft, but it was resurveyed using accurate GPS measurements and found to be eight feet higher. Until the 1980s, Ordnance Survey maps gave its height as 3,010 ft, and so the new measurement confirms that the earlier survey was correct.
