Alaskan Amber

Here is an interesting story on amber. The Inuit people in Alaska is known to have collected amber from northern beach gravels between Harrison Bay and Smith Bay on the Artic Ocean
because with (geologic) time and erosion the fossil resin may have been exposed, loosened and tumbled by rivers or washed out to sea + since amber floats in seawater, again with time the currents may have deposited amber chunks along the Alaskan coast in a random fashion. The locals, according to John Sinkankas, who is an expert on North American gemstones, referred to the amber as auma, meaning live coal. From a gemological perspective the amber specimens from the region showed familiar inclusions such as gas bubbles, network of fissures due to stress, tree debris, mosquito, spiders, beetles, ants, and bees.
