Siah Koh, which translates from Persian as 'Black Mountain,' is a name applied to several different mountain ranges across western and central Afghanistan. One of the most prominent is located in Herat province. These ranges are typically arid, rugged, and characterized by their dark-colored rock, which gives them their name. While not as high as the peaks of the Hindu Kush, they are significant geographical features that shape the local landscape and weather patterns. The environment is harsh and dry, with sparse vegetation. The valleys located between the mountains support limited agriculture, heavily dependent on seasonal rainfall and streams. Historically, these ranges have often served as formidable barriers, isolating communities and making travel and communication difficult.
