NFST Map and Route Analysis 2

Question 1

On a topographic map, contour lines that are spaced very close together indicate:

Accepted Answer

A steep, rapid change in elevation

Answer

Closely spaced contour lines represent rapid elevation change, meaning the terrain is very steep.

Question 2

A map scale of 1:24,000 means that one inch on the map equals how many feet on the ground?

Accepted Answer

2,000 feet

Answer

At 1:24,000 scale, one inch equals 24,000 inches on the ground, which converts to 2,000 feet.

Question 3

Which map symbol typically represents a perennial (year-round) stream on a USGS topographic map?

Accepted Answer

A solid blue line

Answer

Solid blue lines represent perennial streams that flow year-round on USGS topographic maps.

Question 4

When planning a wilderness route, a drainage divide (ridgeline) on a topographic map is best identified by:

Accepted Answer

Contour lines that form U-shapes pointing uphill

Answer

Ridgelines appear as U-shaped contour lines opening toward lower elevations, indicating high ground between drainages.

Question 5

A valley or drainage on a topographic map is identified by contour lines that:

Accepted Answer

Form V-shapes pointing uphill toward higher elevation

Answer

Valleys appear as V-shaped contour lines with the V pointing toward higher elevation (uphill).
