Read a Topo
Looking at topo lines and visualizing real terrain takes practice. Use the two views above to match features to map.
» Check the interval (distance) between contour lines. If the elevation changes quickly—like rising 500 feet vertically over
a horizontal distance of 500 feet, you’re looking at a 45-degree slope that—in snow—is too steep to ascend without roping up.
» Study the way the contour lines come together to form ridges and saddles, key landmarks for route planning.
» Beware of climate effects: The permanent snowfield on this map might have disappeared since the map was made.
