We go beyond contours and creases by developing a new type of line to draw the suggestive contour Sug gestive contours are lines drawn on clearly visible parts of the sur face where a true contour would 64257rst appear with a minimal change in view Most maps have co n tour lines every 10 m There are certain fe a tures you will have to recognise such as Hill top Valley or re entrant Ridge Spur Saddle pass col brPage 2br Uniform gentle slope Contour lines evenly spaced and wide apart indicate a Depict Shape?.

Imagine that the red line represents a geologic contact of some sort. Given that it doesn’t parallel contours we know it isn’t horizontal, and given that it doesn’t cut straight across contours we know it isn’t vertical. Can we tell something about its orientation? .
