I'm down in Juneau and don't really make it to Anchorage much, but will be going by the store next time I'm up there. There are several trees and bushes that could produce great bows. Pick up "Alaska Trees and Shrubs" by leslie A. Viereck and Elbert L. Little, Jr. you can cross reference everything that grows near you with the TBB series and this site. There are several that we don't share in common, but birch, service berry and some special dense spruce that grows in high steep areas, are what you do have available.
