Bolan Pass
Maps show India’s boundaries as officially depicted by the Government of India. Rivers, ranges and regions are drawn from Natural Earth’s public-domain data and are approximate.
Named by NCERT, with the Khyber, as one of the few passes through the north-western mountains.
📘 NCERT Class 11, India: Physical Environment, Ch. 1 (India – Location) ↗
How we check: every fact is written from NCERT Class 11, India: Physical Environment (chapters 1–3), and our build fails unless key phrases from each passage are found in the chapter’s own text. Lengths, heights and areas are given only as NCERT gives them. Shapes come from Natural Earth’s public-domain physical data; features with no reliable map data are described but not drawn.
