text_A: When Alaska became a state in 1959, section 4 of the Alaska Statehood Act provided that any existing Alaska Native land claims would be unaffected by statehood and held in status quo. Yet while section 4 of the act preserved Native land claims until later settlement, section 6 allowed for the state government to claim lands deemed vacant. Section 6 granted the state of Alaska the right to select lands then in the hands of the federal government, including the entirety of Native territory. As a result, nearly from the public domain would eventually be transferred to the state. The state government also attempted to acquire lands under section 6 of the Statehood Act that were subject to Native claims under section 4, and that were currently occupied and used by Alaska Natives. The federal Bureau of Land Management began to process the Alaska government's selections without taking into account the Native claims and without informing the affected Native groups.
text_B: Did Section 6 include any restriction on the federal lands that Alaska could choose?
NO.
