Sentaçaan
The Sentachan joins the Adycha in the mountainous Yana basin of northeastern Yakutia. The nearby Nelgese also feeds the Adycha, which carries these waters north to the Yana and ultimately the Laptev Sea. Steep valley sides and wooded slopes surround the river courses, while snow and ice dominate the long winter. The brief summer releases the streams and brings renewed flow to the larger river.
