Topographic maps help to show the shape of the land
With contour lines and symbols you’ll be able to understand
That points that all had the same
Elevation then became
A single, unbroken line
Seldom will branch or intertwine
The circles are hills or holes, and the scale will indicate
The contour intervals; in between you can estimate
Chorus: A map, a map, a topographic map
A map, a map, a topographic map
A steeper slope is known from the lines being close together
A gentler slope is shown by the spacing being wider
Darker contour lines
Separated by four others
These are the index lines
And they often have little numbers
Showing elevation from sea level, above or below
In meters or feet are given, which the scale will always show
Brown lines will point upstream when crossing rivers or creeks or valleys
And as confusing as it may seem, the branching of blue tributaries
Will point where water flows
And one more thing to know is...
The U.S. Geological Survey is a governmental agency
That surveys, maps, and studies landforms and geologic activities
And puts benchmarks at certain locations, and
The U.S.G.S. has colors, on their topo maps are seen
Black is for what’s man-made; water is blue; and plants are green
