topo maps
Contour line drawings
Topo maps is short for topographic maps—detailed maps showing terrain features through contour lines, which connect points of equal elevation.
The lines reveal hills, valleys, and slopes at a glance.
Hikers, surveyors, and geologists rely on topo maps to understand landscape before encountering it: I grabbed the topo maps before heading into the backcountry.
