Biorka Island
Island in Sitka City and Borough, Alaska, United States
From Wikipedia, the free encyclopedia
Biorka Island is an island near Sitka, Alaska.[1] The National Weather Service has a radar there.[2] The island is also a popular spot to watch sealions. Thus, a 2005 proposal by the State of Alaska to give a parcel of 438 acres (177 ha) on the island to the University of Alaska stirred up a controversy.[3]
The original name in the Tlingit language for the island is Watsíxh ("Caribou").
