What do the colors on the contour map of Mount Bona (5005m) 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 Mount Bona (5005m)?

The contour map of Mount Bona (5005m) 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 Mount Bona (5005m) show?

The elevation profile is a cross-section through Mount Bona (5005m) from west to east, passing through the summit at 5,005m. 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 Mount Bona (5005m)?

At Mount Bona (5005m)'s latitude (61°), the estimated permanent snow line is approximately 1,500m. Since Mount Bona (5005m) reaches 5,005m, about 3,505m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.

Why does Mount Bona (5005m) have elongated ridges?

Mount Bona (5005m) 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.

Contour Map

The topographic contour map of Mount Bona (5005m) in the Saint Elias Mountains 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 5,005m summit). Above 1,500m, the estimated snow line at this latitude, contours transition to cooler tones indicating permanent snow and ice.

Elevation Profile

The east–west elevation profile of Mount Bona (5005m) in the Saint Elias Mountains shows the terrain cross-section through the summit at 5,005m. 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 1,500m marks the approximate elevation above which permanent snow persists year-round.
