What do the colors on the contour map of Jannu (7711m) 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 Jannu (7711m)?

The contour map of Jannu (7711m) 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 Jannu (7711m) show?

The elevation profile is a cross-section through Jannu (7711m) from west to east, passing through the summit at 7,711m. 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 Jannu (7711m)?

At Jannu (7711m)'s latitude (28°), the estimated permanent snow line is approximately 4,500m. Since Jannu (7711m) reaches 7,711m, about 3,211m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.

Why does Jannu (7711m) have elongated ridges?

Jannu (7711m) 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.

Jannu (7711m)

JannuはNepalに位置し、標高7711 mです, Himalayasの一部, Asia. この山はFold Mountainに分類されます。

Jannu, known in Nepal as Kumbhakarna, rises to 7,711 metres in the Kangchenjunga section of the eastern Himalaya. Famed for the sheer, overhanging granite of its north face, it is one of the most technically celebrated peaks of its height, and its difficult 1962 first ascent and later hard routes stand as milestones in Himalayan climbing. It is a fold mountain, uplifted where the Indian and Eurasian plates meet. The site rates it grade 5, its most demanding classification. Lower than the eight-thousanders nearby, Jannu is prized for the steepness and quality of its climbing rather than for altitude, and it attracts accomplished alpinists rather than crowds.

等高線地図

The topographic contour map of Jannu (7711m) 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 7,711m 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 Jannu (7711m) in the Himalayas shows the terrain cross-section through the summit at 7,711m. 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.
