Amber (Tukwila Fm./Renton Fm. [Boundary], Middle to Late Eocene)
1.2 gram amber from Tiger Mountain, King County, WA. Smaller inclusions consist mostly of slightly darker, congealed resin positioned along natural flow lines; this feature is by far most commonly seen among the Indonesian ambers. The few large, dark masses are botanical debris. Image taken under approx. 10x magnification with a Belomo Triplet loupe. This amber is middle to late Eocene in age (about 41.3-33.9 Ma), and comes from coal seams along the boundary between the upper Tukwila/lower Renton Formations.
