Be very careful about what you are asking people for (or do). In case everyone is not aware:
§41.35.190(c) of the Alaska Historic Preservation Act (Citation: Alaska Historic Preservation Act (Alaska Stat. §41.35.010 through §41.35.240). Dates Enacted : 1971, amended 1988 and 1993) does state that "No person may unlawfully destroy, mutilate, deface, injure, remove or excavate a gravesite or a tomb, monument, gravestone or other structure or object at a gravesite, even though the gravesite appears to be abandoned, lost or neglected." Native Alaskan consent is required for excavation of native sites and landowner consent is required for excavation on private lands. The Alaska Historical Commission has responsibility for managing and protecting all prehistoric and historic sites in the state and issues permits for excavations. Nothing may diminish cultural rights or responsibilities of persons of aboriginal decent or infringe upon their right of possession, and use of those resources and local cultural groups may obtain from the state resources of respective cultural if meet certain criteria. Violations of the Historic Preservation Act provisions are considered a class A misdemeanor and civil penalties may be assessed up to $100,000 per violation and up to one year in jail.
Any artifacts found should be reported to the State of Alaska's Historic Preservation Office, and should not be removed. If the artifact is part of NAGRA or is selected under 14(h)(1) of ANCSA as amended by ANILCA, there could be some very serious trouble.
