The Kusilvak Mountains (Ingrill’er, Manialnguq in Yup'ik) is a mountain range of the Yukon Delta in Kusilvak Census Area, Alaska,[1] to which the range gives its name.[2] The mountains are adjacent to Nunavakanuk Lake. At their highest point they reach 2241feet and span over 5 miles across.
The mountains were called Ingieguk on Russian maps, probably from the Yup'ik language name for mountain.
