map is essential to successfully finding a ghost town. USGS topographical maps are useful because they show the terrain and lay of the land as well as feature like roads, structures and mines. As you read this, it would be helpful if you also had your own topographical map to refer to....
Determine the area to be investigated. On a physical or digital map, establish the location of the area to be studied, noting the beginning and ending points. Acquire an elevation profile for this region. Consult a mapping tool such as Google Maps, MapQuest or Garmin for a topographical repr...
The contour interval is the amount of elevation change between each contour line. Contour intervals vary from map to map. Intervals set at 40-feet are common on 1:24,000 scale maps. But many maps, especially small scale maps, have 50-foot or 100-foot intervals. Index contours are the mo...
Simplified trail maps—such as the JPEG images you might find on anational park’swebsite—don’t always include all the information you need for complete navigation. There’s no elevation data, no magnetic declination, and not as many symbols. If you get lost, these trail maps won’t hel...
Contour interval:The change in elevation from one contour line to the next is always the same within the same map. Many maps have either a 40- or 80-foot contour interval: An 80-foot interval simply means that each contour line is 80 vertical feet away from the next closest line. You ...
Most maps use symbols and abbreviations, rather than descriptions, to show where things are. This is to avoid the map being crowded with writing, making it harder to read. The key as to how to read a map is exactly that: a key. Also known as a legend, the key sits in the corner ...

Use these maps to help avoid avalanches by identifying aspect and elevation, slope angle, topography, terrain traps, and avalanche paths.
The great thing about Topographic maps is the large amount of useful information they provide. Besides showing you things like elevation and steepness of slopes, they also include symbols that represent things like roads and trails, railroads, buildings, streams and waterways, water tanks, campgrounds...
Traveling in avalanche terrain is an inherently dangerous activity. You should not travel in avalanche terrain until you and your partners undergoavalanche safety trainingand are competent in the use ofavalanche safety gear(beacon, shovel, probe). Maps serve as a supplement to avalanche safety traini...
