 Despite numerous observations and publications about the growing glacier in the late 1990s and early 2000s, no move was made to give the glacier a permanent and official name until late 2004, after the current eruptive cycle began and the new dome began to split the glacier. At that time, a proponent from the Cowlitz tribe suggested the name "Tulutson Glacier," from the Cowlitz language word for ice. In March 2005, the Washington State Board on Geographic Names chose Tulutson over three other contenders (Crater, Spirit, and Tamanawas), and so Tulutson Glacier became the de facto name.
