Trollhul (2977m) is a glacial horn in Antarctica. Grade 5/5: extreme expedition where supplemental oxygen is typically required. A well-regarded peak in its region, offering accessible terrain and panoramic views for fit hikers.
The topographic contour map of Trollhul (2977m) shows sharply angular contours converging to a pyramidal peak. 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 2,977m summit). Above 300m, 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 Trollhul (2977m) shows the terrain cross-section through the summit at 2,977m. 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.
Frequently Asked Questions
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.
The contour map of Trollhul (2977m) 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.
The elevation profile is a cross-section through Trollhul (2977m) from west to east, passing through the summit at 2,977m. 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.
At Trollhul (2977m)'s latitude (72°), the estimated permanent snow line is approximately 300m. Since Trollhul (2977m) reaches 2,977m, about 2,677m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.
Trollhul (2977m) is a glacial horn, carved into its pyramidal shape by cirque glaciers eroding three or more sides. The angular, converging contours on the map reflect these steep, frost-shattered arêtes.
