SLOPE.Hachures:These are small straight lines drawn on the map ALONG the direction of MAXIMUM slope, running across the contours.They have given an idea about the differences in the slope of the ground.By their thickness and overall DENSITY, they provide a general sense of steepness.When the slope is steep, the lines or hachures are thick and close together; when the slope is gentle, they are thinner and farther apart.The darkest portions of a hachures map represent crags and very steep slopes, while the lighter shades show the gentler slopes.The white parts show plateaux, very high-level MOUNTAIN tops, hillside shelves, or deep level valley bottoms.
