The fifth edition of the paper map uses high-resolution LIDAR elevation data for the slope shading, elevation contours, and relief shading. The LIDAR elevation data is accurate to within a few feet.
As with the third and fourth editions, the fifth edition has "reddish" slope shading to help you identify slopes that are approximately 30° or steeper. The slope shading is much more accurate on the fifth edition.
The Wasatch Backcountry Skiing Map project set out to catalog all the named ski runs in the central Wasatch. About 1,200 named features have been identified and mapped. The interactive map can be viewed for free at WasatchBackcountrySkiing. Available for sale is a waterproof folded 24x36" map of all the data available. Unfolded single and double-sided maps are also available at http://stevesmap.com
Example: Here's a portion of the map near the top of Days Fork. Want to know exactly which run Oingo Boingo is?
Have you heard about the great skiing in Hobbs Chute and want to know exactly where it is? The paper map includes an index with grid coordinates to find a location on the paper map, or you can use the "online location number" to display the location on WasatchBackcountrySkiing.com.

This map is available to emergency response personnel for dispatching rescues. In a call for help, reporting that you are near Baker Spring will avoid explaining to a dispatcher that you are on Gobbler's Knob, between Big Cottonwood Canyon and Millcreek, in view of the valley, NW of the summit, and so on. Provide the run name and response personnel will have your exact coordinates.
