Honorary Indian Chief
The Kaska Dena nation bestowed on Curragh CEO Cliff Frame an honorary name in the Kaska Dena tongue. He was called, by the Kaska, "Ano Sede," (he who travels far) the name of a previous Kaska chief known for his wide-ranging travels. This deeply moving ceremony symbolized the relationship that Curragh and the Kaska Dena had nurtured.
