Biorka Island

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").
