Two exceptionally fluorescent pieces of amber from Tiger Mountain, King County, WA. These were illuminated with a 140 lumen LED penlight, not a long wave UV light; this is a surprising feature for amber of this locality, as blue amber is only well-documented to come from the Dominican Republic, Indonesia, and Chiapas. This amber is middle to late Eocene in age (about 41.3-33.9 Ma), and comes from coal seams along the boundary of the upper Tukwila/lower Renton Formations.
