This series of maps only shows national political boundaries, and does not show provinces and Pakistan's "agencies". However, North and South Waziristan Agency lies between Gul Kach, in the south, to Thal, in the north, along Pakistan's frontier with Afghanistan. The terrain on the border is mountainous, with only a few usable routes open. Winter time travel is even more limited and hazardous. Note the proximity to Khowst.
