What do the colors on the contour map of Mount St. Helens (2549m) 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 St. Helens (2549m)?

The contour map of Mount St. Helens (2549m) 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 St. Helens (2549m) show?

The elevation profile is a cross-section through Mount St. Helens (2549m) from west to east, passing through the summit at 2,549m. 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.

Why does Mount St. Helens (2549m) have a crater?

As a stratovolcano, Mount St. Helens (2549m) 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 St. Helens (2549m) in the Cascade Range shows near-circular, closely spaced contours indicating steep conical 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 2,549m summit).

Elevation Profile

The east–west elevation profile of Mount St. Helens (2549m) in the Cascade Range shows the terrain cross-section through the summit at 2,549m. The color gradient transitions from green (valley floor) to white (summit zone), with the red summit marker indicating the peak.
