What do the colors on the contour map of Mount Blackburn (4996m) 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 Blackburn (4996m)?

The contour map of Mount Blackburn (4996m) 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 Blackburn (4996m) show?

The elevation profile is a cross-section through Mount Blackburn (4996m) from west to east, passing through the summit at 4,996m. 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 Blackburn (4996m)?

At Mount Blackburn (4996m)'s latitude (62°), the estimated permanent snow line is approximately 1,500m. Since Mount Blackburn (4996m) reaches 4,996m, about 3,496m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.

Why does Mount Blackburn (4996m) have a crater?

As a stratovolcano, Mount Blackburn (4996m) was built by alternating layers of lava and ash. The summit crater is visible on the contour map as a small depression within the tightly spaced concentric contours near the peak.

Contour Map

The topographic contour map of Mount Blackburn (4996m) shows near-circular, closely spaced contours indicating steep conical slopes. 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 4,996m 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 Blackburn (4996m) shows the terrain cross-section through the summit at 4,996m. 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.
