What do the colors on the contour map of Nanda Devi (7816m) 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 Nanda Devi (7816m)?

The contour map of Nanda Devi (7816m) 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 Nanda Devi (7816m) show?

The elevation profile is a cross-section through Nanda Devi (7816m) from west to east, passing through the summit at 7,816m. 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 Nanda Devi (7816m)?

At Nanda Devi (7816m)'s latitude (30°), the estimated permanent snow line is approximately 3,800m. Since Nanda Devi (7816m) reaches 7,816m, about 4,016m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.

Why does Nanda Devi (7816m) have elongated ridges?

Nanda Devi (7816m) 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.

Nanda Devi (7816m)

Nanda Devi位于India，海拔7816米, 属于Himalayas, Asia. 该山峰被归类为Fold Mountain。

Nanda Devi is the highest mountain lying entirely within India, reaching 7,816 metres in the Garhwal Himalaya of Uttarakhand. Ringed by a wall of high peaks that enclose the Nanda Devi Sanctuary, it was long among the most inaccessible of the great summits, and its inner basin was not entered by explorers until the 1930s. It is a Himalayan fold mountain, held sacred in regional tradition and named for a revered goddess. The site rates it grade 5, an extreme classification, and access is now tightly restricted to protect the surrounding biosphere reserve. Its guarded approaches and protected status keep climbing exceptionally rare.

等高线地图

The topographic contour map of Nanda Devi (7816m) 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 7,816m summit). Above 3,800m, the estimated snow line at this latitude, contours transition to cooler tones indicating permanent snow and ice.

海拔剖面

The east–west elevation profile of Nanda Devi (7816m) in the Himalayas shows the terrain cross-section through the summit at 7,816m. 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 3,800m marks the approximate elevation above which permanent snow persists year-round.
