"This mountain north of Cowichan Bay is named after one of the fiercest of the war chiefs of the Cowichans. In 1844 he led an attack on Fort Victoria after the HBC tried to collect damages for cattle which his band had slain. Because of his frequent murders, he was banished at last by his fellow Indians, and took up residence in a cave on the side of [this mountain]. He had some fourteen wives living with him, most of whom had been widowed by him. Going to Kuper Island to acquire a new wife, Tzuhalem was slain by the woman's husband before Tzuhalem could kill him."
