The southern half of the icefield is named the Silverthrone Glacier and flows west, joining the Klinaklini Glacier just above that glacier's terminus, where its outflow is short but very large, and joins the Klinaklini River within a few kilometres. The Klinaklini Glacier constitutes the northern half of the icefield, and off its northwest edge a glacial tongue produces the head of the Machmell River. The name Ha-Iltzuk Icefield does not appear in government gazettes. The term is almost certainly a phonetic spelling of hailtzaq - the Heiltsuk language pronunciation for the term Heiltsuk.
