An international team of researchers has conducted the largest radar survey in Alaska's history in the Sitka National Historical Park. The use of powerful georadars made it possible to find the ruins of the legendary Shisgi Nou (Young Fort) fort. This is a sacred place for the Frog clan of the Tlingit people and the site of the main battle between Russian colonists and American Indians (in fact, also Russian colonists of an older wave of migration - ed. By Tekhkult).
The development of Alaska by the Russians has never been an easy and peaceful affair, largely due to the influence of American trading companies who wanted to get the resources here, but at that time did not have such an opportunity. We are talking about the first decade of the 19th century - Russia at that time is busy with the threat of invasion by Napoleonic troops, and a second war with Britain for independence was brewing in the United States. With the virtual absence of military power in the Alaska region, both sides actively attracted local Indian tribes to their side.
In 1802, the united Tlingit tribes attacked and destroyed the Mikhailovsky Fortress on Sitka Island. The Indians understood that the Russians would definitely return to take revenge, and in order to detain or even scare them away, they built a wooden fort of Shisgi Nou. The battle took place in 1804 - due to the cowardice of the Indian allies, the assault on the fort failed, but as a result of the siege it was still captured and completely destroyed. The Tlingit tribes who participated in the war were expelled from their ancestral lands, and the location of Shisgi Nou was forever lost.
However, modern technology does allow miracles to be performed. Scientists scanned more than 17 hectares of the park, studied dozens of sites until they found underground formations of an unusual trapezoidal shape. The traces of structures found there correspond to the surviving descriptions of both the Tlingits and the Russian participants in the assault. This is a landmark event in the study of the history of Alaska and a clear demonstration of the use of GPR in archaeological operations.
