What do the colors on the contour map of Mount Siple (3110m) 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 Siple (3110m)?

The contour map of Mount Siple (3110m) uses a 50m contour interval. This means each line represents a 50m change in elevation. Closely spaced contours indicate steeper terrain, while widely spaced contours show gentler slopes.

What does the elevation profile of Mount Siple (3110m) show?

The elevation profile is a cross-section through Mount Siple (3110m) from west to east, passing through the summit at 3,110m. 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 Siple (3110m)?

At Mount Siple (3110m)'s latitude (73°), the estimated permanent snow line is approximately 300m. Since Mount Siple (3110m) reaches 3,110m, about 2,810m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.

Why does Mount Siple (3110m) have gentle slopes?

Mount Siple (3110m) is a shield volcano, built almost entirely from fluid lava flows. The contour map shows widely spaced lines, reflecting slopes that rarely exceed 5–10 degrees — much gentler than a stratovolcano.

Topographic Analysis

Contour Map

The topographic contour map of Mount Siple (3110m) shows widely spaced, gently curving contours reflecting broad, low-angle slopes. Contour lines are drawn at 50m intervals, with index contours (thicker lines) every 250m. The hypsometric color scale ranges from green (lower elevations) through yellow and orange to white (highest elevations near the 3,110m summit). Above 300m, 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 Siple (3110m) shows the terrain cross-section through the summit at 3,110m. 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 300m marks the approximate elevation above which permanent snow persists year-round.
