Question 1

Which map datum is the standard for most USGS topographic maps used in US outdoor education?

Accepted Answer

NAD 83

Answer

NAD 83 (North American Datum 1983) is the standard horizontal datum for most current USGS topographic maps and is compatible with modern GPS devices.

Question 2

In a CORE outdoor education class, a student should practice navigation skills in what progressive order?

Accepted Answer

Map reading → compass → GPS as backup

Answer

Best practice teaches map reading and terrain association first, then compass use, with GPS as a backup tool — ensuring students can navigate without technology.

Question 3

What is the standard scale used on most USGS 7.5-minute topographic maps?

Accepted Answer

1:24,000

Answer

USGS 7.5-minute topographic quadrangle maps use a scale of 1:24,000, meaning one inch on the map equals 24,000 inches (2,000 feet) on the ground.

Question 4

Which directional method is most reliable when electronic devices fail in the backcountry?

Accepted Answer

Map and baseplate compass

Answer

A topographic map and baseplate compass require no batteries or signal and remain functional in all conditions, making them the most reliable backcountry navigation tools.

Question 5

What does a 'saddle' look like on a topographic map?

Accepted Answer

Two hilltops connected by a low point shown as an hourglass shape in contours

Answer

A saddle appears as two high points flanking a lower connecting ridge, creating an hourglass or figure-eight pattern in the contour lines.
