Pen yr Ole Wen (978m)

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 Pen yr Ole Wen (978m) uses a 25m contour interval. This means each line represents a 25m change in elevation. Closely spaced contours indicate steeper terrain, while widely spaced contours show gentler slopes.

The elevation profile is a cross-section through Pen yr Ole Wen (978m) from west to east, passing through the summit at 978m. 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.

Pen yr Ole Wen (978m) was formed by tectonic folding, which compressed rock layers into long, parallel ridges. The contour map shows elongated lines that follow the axis of the fold, rather than circular patterns.
