Gulcha
Gulcha lies in a broad mountain valley north of the Alay range. Three streams meet here to form the Kurshab, which flows toward the Kara Darya and the Fergana basin. Snow and glaciers feed the river from the high Alay slopes, while fields occupy the valley floor and pastures rise above it. The valley opens a route between the more densely settled lands around Osh and the higher country beyond the mountain passes to the south.
