Uses of Topographic Maps

• Why don’t we just use a picture?

• Who can use it?

• engineers, foresters, land use planners, hikers, ... virtually anyone who travels outdoors

• “the cross sectional shape of a valley stream valleys in mountainous areas is usually "V" shaped.  This shaped is changed when a glacier flows down the valley.  The bottom of the valley will be rounded while the sides of the valley will be steepened. The result is a U shaped valley with steep sides and a rounded valley”

Why do we care?

• Who in here sleds?

• Skiers or boarders?
