What do the colors on the contour map of Annapurna (8091m) 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 Annapurna (8091m)?

The contour map of Annapurna (8091m) 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 Annapurna (8091m) show?

The elevation profile is a cross-section through Annapurna (8091m) from west to east, passing through the summit at 8,091m. 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 Annapurna (8091m)?

At Annapurna (8091m)'s latitude (29°), the estimated permanent snow line is approximately 4,500m. Since Annapurna (8091m) reaches 8,091m, about 3,591m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.

Why does Annapurna (8091m) have elongated ridges?

Annapurna (8091m) 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.

The topographic contour map of Annapurna (8091m) 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 8,091m 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 Annapurna (8091m) in the Himalayas shows the terrain cross-section through the summit at 8,091m. 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.
