the provisional cnpk terminus & conventionally
depicted cninpk position
which is favored by pakistan
is shown here as a tricolor trijunction at karakoram
pass

but as you probably know or can gather from the map
the entire triarea is in multiple dispute

& the de facto position
which is favored by india
appears to be at or near indira col or indirakoli pass
about 100 km wnw of karakoram pass
where saltoro ridge meets karakoram ridge east of
siachen glacier

http://in.rediff.com/news/2005/may/26siac.htm

both karakoram pass & indira col are named & shown in
detail here
albeit strangely unassociated with any borders
http://www.lib.utexas.edu/maps/ams/india/ni-43-04.jpg

look for karakoram pass at center far right & indira
col at upper leftish

but since the google earth border overlays & jespers
pushpin already have the provisional conventional &
rather unreal position covered at karakoram pass
my attached best guessed tripoint stretching diagram
has tried instead for the actually effective de facto
position at indira col
