I think you have your directions twisted. Notice the directional arrow way on the left. That makes Mandata NW or so from Wuzhgai.
It does look like snow, but actually those are clouds which were present in the overhead imagery before it was draped over the elevation model. As I understand it, we are strong in the Khost area, and maintain a presence up near the border along the Khost-Miram Shah road as well. Hard to say how strong or dominant, but many of the US border "incursions" reported by Pakistan have occurred in this area.
The area you refer to is the eastern arm of the Shawal area in Afghanistan, a rugged "no man's land" where AQ is rumored to hide. There are several other such areas, the Pakistani Shawal District, the border areas north and northeast of Khost near Parachinar and Jaji, even the mountains north east of Garduz and northwest of Khost. As I understand it, the Parachinar area has been reported to be quiet lately, with most of the attention being focused south west of Miram Shah and northwest of Wana.
The overlays originated as 30 meter per pixel imagery but have been degraded through rendering and compression. Lakes are expected to appear if larger than 100 meters in diameter, though just barely. You can figure that every watershed will have a drainage channel, either dry, intermittant, or fulltime, and these are often blocked by talus flow to form alpine lakes. Although Pakistan is known for its dry areas and has significant water shortages, the Shawal District is known for its thick forests, indicating adequate rainfall to maintain full time drainage systems.
