About This Mountain
South Sister (3157m) is a stratovolcano in the Cascade Range, United States. Grade 2/5: moderate trek requiring good physical fitness. This stratovolcano rises steeply from the surrounding terrain with a classic conical profile.
The topographic contour map of South Sister (3157m) 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 3,157m summit).
Elevation Profile

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 South Sister (3157m) 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 South Sister (3157m) from west to east, passing through the summit at 3,157m. 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.
As a stratovolcano, South Sister (3157m) 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.
