What do the colors on the contour map of Ngadi Chuli (7871m) mean?

The contour map uses a hypsometric color scale where green represents lower elevations, yellow and orange indicate mid-range altitudes, and white marks the highest zones near the summit. Thicker contour lines (index contours) are drawn at wider intervals to help you quickly estimate elevation.

What is the contour interval for Ngadi Chuli (7871m)?

The contour map of Ngadi Chuli (7871m) uses a 100m contour interval. This means each line represents a 100m change in elevation. Closely spaced contours indicate steeper terrain, while widely spaced contours show gentler slopes.

What does the elevation profile of Ngadi Chuli (7871m) show?

The elevation profile is a cross-section through Ngadi Chuli (7871m) from west to east, passing through the summit at 7,871m. It reveals the mountain's shape, steepness, and relative height compared to the surrounding terrain. The horizontal axis shows distance in kilometers from the peak.

What is the snow line on Ngadi Chuli (7871m)?

At Ngadi Chuli (7871m)'s latitude (28°), the estimated permanent snow line is approximately 4,500m. Since Ngadi Chuli (7871m) reaches 7,871m, about 3,371m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.

Why does Ngadi Chuli (7871m) have elongated ridges?

Ngadi Chuli (7871m) was formed by tectonic folding, which compressed rock layers into long, parallel ridges. The contour map shows elongated lines that follow the axis of the fold, rather than circular patterns.

Ngadi Chuli (7871m)

Ngadi ChuliはNepalに位置し、標高7871 mです, Himalayasの一部, Asia. この山はFold Mountainに分類されます。

Ngadi Chuli, also known as Peak 29, rises to 7,871 metres in the Mansiri Himal of Nepal, set between Manaslu and Himalchuli. Its climbing history is unusually murky: early claims of a summit were disputed, and the mountain is often listed among the highest peaks whose full ascent record remains uncertain. It is a Himalayan fold peak, formed by the collision of the Indian and Eurasian plates. The site rates it grade 5, an extreme classification that assumes a full expedition with supplemental oxygen. Steep and infrequently attempted, it ranks among the quieter high summits along this stretch of the Nepalese Himalaya.

等高線地図

The topographic contour map of Ngadi Chuli (7871m) in the Himalayas shows elongated parallel contours following the ridge axis. Contour lines are drawn at 100m intervals, with index contours (thicker lines) every 500m. The hypsometric color scale ranges from green (lower elevations) through yellow and orange to white (highest elevations near the 7,871m summit). Above 4,500m, the estimated snow line at this latitude, contours transition to cooler tones indicating permanent snow and ice.

標高プロフィール

The east–west elevation profile of Ngadi Chuli (7871m) in the Himalayas shows the terrain cross-section through the summit at 7,871m. The color gradient transitions from green (valley floor) to white (summit zone), with the red summit marker indicating the peak. The dashed blue snow line at 4,500m marks the approximate elevation above which permanent snow persists year-round.
