Where is the border in Kashmir?
The same mountain region can look different depending on what a map means by its boundary lines.
Entirely Indian
Indian government maps show the whole of Jammu and Kashmir and Ladakh with a solid, undifferentiated border — India's constitution treats it as fully Indian territory, no exceptions shown.
Marked contested
Pakistani maps draw the region with a dotted boundary rather than a solid one — a deliberate signal that its status remains unsettled, not incorporated into either country.
Dashed Line of Control
Most international maps draw the 1972 Line of Control as a dashed border — the de facto military boundary, presented as a ceasefire line rather than a settled international one.
The mountains do not move. The political meaning of the line does. Three countries currently administer pieces of the old princely state: India holds and governs the largest share (Jammu, the Kashmir Valley, and Ladakh); Pakistan administers Azad Kashmir and Gilgit-Baltistan in the west and north; China holds Aksai Chin in the east, ceded to it by Pakistan in a 1963 border agreement that India does not recognize. India and Pakistan have fought three wars substantially over the territory since 1947, and the Line of Control dividing Indian- and Pakistani-administered areas was set by the 1972 Simla Agreement — a ceasefire line, not either side's claimed border.
A line on a map can mean a settled border, a ceasefire, or a claim, and maps often draw them the same way. Before reading a line as a fact, ask what kind of line it is.
Is the line showing control, a claim, or an agreed border?

A three-way split like this isn't unique to the Himalayas — Western Sahara is claimed, administered, and internationally classified three different ways at once, by Morocco, the Polisario Front, and the UN respectively.
Indian law (the Cartography Act's 2011 rules) treats any map that shows Kashmir's boundary differently as illegal to sell or distribute in India, so global map providers that want to operate there quietly adjust what they show — one boundary style inside India, another everywhere else. It's the same location-dependent trick as Google Maps showing "Gulf of America" only to users inside the United States: a single map product, quietly rendering a different political reality depending on where you're viewing it from.
The other end of the Himalayas: Arunachal Pradesh
India’s eastern border is drawn three ways too. Arunachal Pradesh, in India’s far northeast, is an ordinary Indian state on Indian maps and part of China on Chinese ones.
An ordinary state
Indian maps show Arunachal Pradesh like any of its other states: a plain internal boundary, nothing to suggest it is contested.
“South Tibet”
Chinese government maps show the area as Chinese territory, “Zangnan,” with the same solid border as any other province.
Dashed, disputed
Most international maps show the area under Indian administration, but mark the boundary with China as a disputed, dashed line.
The line in question is the McMahon Line, drawn in 1914 between British India and Tibet. China has never accepted it, arguing Tibet had no authority to sign away Chinese territory. In October 1962 Chinese forces crossed it and advanced deep into the state, then declared a ceasefire and withdrew a month later. India has administered the area ever since, and since 2017 China has repeatedly issued its own Chinese names for the state’s towns and landmarks.
