What do the colors on the contour map of Thunderbolt Peak (4257m) 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 Thunderbolt Peak (4257m)?

The contour map of Thunderbolt Peak (4257m) 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 Thunderbolt Peak (4257m) show?

The elevation profile is a cross-section through Thunderbolt Peak (4257m) from west to east, passing through the summit at 4,257m. 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 Thunderbolt Peak (4257m)?

At Thunderbolt Peak (4257m)'s latitude (37°), the estimated permanent snow line is approximately 3,800m. Since Thunderbolt Peak (4257m) reaches 4,257m, about 457m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.

The topographic contour map of Thunderbolt Peak (4257m) in the Sierra Nevada shows contours reflecting the unique geological character of the terrain. 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 4,257m summit). Above 3,800m, the estimated snow line at this latitude, contours transition to cooler tones indicating permanent snow and ice.
