I lived in Pasawar Pakistan when I was 5-8 years old. Visited Afganistan around the Kyber Pass area. Used to see the Hindu Kush out my window every morning. Some times K2. This dont look like the Hindu Kush. Parts of North Africa maybe, Tunishia, Lybia, Chad, Sudan. Also parts of the American South West.
But that airfeild at 9k on the edge of an escarpment. Maybe a relic from Alexander the Greats taking a few fortresses in Afganistan.
