Aldan River
"Russian arrival:" In 1639 Ivan Moskvitin left Brutalsk on the Aldan River, went southeast up the Maya, crossed the mountains and reached the mouth of the Ulya River after 11 weeks. He built winter quarters and next year sent parties south to Uda Gulf and north to Taui Bay. In 1646 Vasili Poyarkov sailed north from the Amur and re-used Moskvitin's huts on the Ulya. In 1647 Semyon Selkovnik built winter quarters at Okhotsk and in 1649 a proper ostrog was built there. In 1651-57 Mikhail Stadukhin made a poorly documented journey along the whole coast from Penzhina Bay to Okhotsk. Okhotsk was burned down by the Lamuts in 1653 or 54. They revolted again in 1665 and 1677.
