Contour Line

What is a contour line?

A contour line is a curved line on a topographic map that connects points of equal elevation above sea level. These lines help hikers and backpackers visualize the three-dimensional shape of terrain on a flat map, showing hills, valleys, ridges, and slopes. Lines close together indicate steep terrain, while widely spaced lines represent gentle slopes, making contour lines essential for route planning, estimating hiking difficulty, and navigation in the backcountry.

Topographic Map

A topographic map is a detailed representation of terrain that shows elevation changes, landforms, and natural features using contour lines and symbols. These maps are essential tools for hikers and backpackers to navigate wilderness areas, plan routes, identify water sources, campsites, and potential hazards. The contour lines indicate elevation and steepness of terrain, helping outdoor enthusiasts understand the difficulty of their planned route and navigate safely even without GPS technology.
