Showell Styles’ life had two principal themes, mountains and writing. Sometimes these coincided, sometimes they were far apart. The first eleven years of his working life were in banking, however he gave this up to walk across Europe and then joined the World War II Royal Navy as a gun layer, rising to the rank of Commander.
He joined the MAM after the war and spent much of his time in exploring the more out of the way crags of Snowdonia such as the Moelwyns, Moel Hebog, Mel y Gest and the crags between Moel Siabod and Croesor, publishing miniguides to some of these in the MAM Journal. He wrote prolifically for the MAM Journal often making wry and humorous comments on the climbing world, sometimes using the pen name C.L.Inker. He climbed widely, writing books about climbs in Norway and the Himalayas. Much of his writing was instructional or just plain whimsical and perhaps he is best remembered for his “Mountaineer's Weekend Book” and “Mountaineer's Bedside Book”, extraordinary collections of lists, rhymes, songs, first aid hints and much more, notably the well-loved “Ballad of the Idwal Slabs”, written one Christmas Day by the fire in Glan Dena having been banished from the kitchen while others cooked the Christmas goose. Under the pseudonym Glyn Carr he wrote a series of whodunits featuring the unlikely climbing detective “Filthy” Lewker. Perhaps his most successful and most long lasting project, perhaps not known to many climbers, was his long running series of novels set in the Royal Navy of 1740 to 1825.
Many years an MAM member and sometime President, he attended and led many meets including two to Norway. Through all this time he lived with his family overlooking the sea near Porthmadog and in his later years became a loyal member of his local climbing club, Clwb Dringo Porthmadog.
