About this app

In an effort to make mountain driving a little safer for RV and truck drivers, we have been collecting and publishing information on mountain passes and steep grades since 1993. Mountain Directory West includes descriptions of over 400 locations in eleven western states, and Mountain Directory East includes descriptions of over 300 locations in eleven eastern states.

Over 130,000 printed copies of Mountain Directory West and Mountain Directory East have been sold. In response to many customer requests, both Mountain Directory West and Mountain Directory East are now available as phone and tablet apps. Anyone who has experience driving large or heavy vehicles in mountainous terrain will know the value of this information. And those who don't have mountain driving experience need it even more. Learning the hard way can be, well, hard.

Mountain Directory West includes locations and descriptions of over 400 mountain passes and steep grades in the following states: Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. Mountain pass locations are marked with a yellow triangle on beautiful color relief maps. Touching a yellow triangle on the screen displays text that describes that location. The text includes how long the grade is, how steep (%) it is, if it is two lane, three lane, or four lane, if it has sharp curves, switchbacks, escape ramps, sharp drop offs, etc.

The 300 locations covered in Mountain Directory East are in the states of Vermont, New Hampshire, New York, Massachusetts, Pennsylvania, Maryland, West Virginia, Kentucky, Virginia, North Carolina, and Tennessee. Some people are under the impression that the grades in the eastern mountains are not as serious as the grades in the western mountains. Apparently this is because the elevations are not as high in the eastern states. But elevation alone is not the problem-it is the change in elevation that makes a grade potentially hazardous. Many times, eastern grades are even steeper than western grades, often in the 8 to 10% range. And because of the terrain, the roads are often narrower and more winding than the roads out west.

The price for the Mountain Directory West is $16.99 and the price for the Mountain Directory East is $14.99. The Mountain Directory East and West Combined costs only $24.99, or $7.00 less over buying them individually.

As time goes on, we intend to add much more information and new features to the apps, all of which will be included in free upgrades.

And this is important, the information resides on your device so it is always available even when you are many miles from a cell tower. It is there when you need it most.

The app is a bit cumbersome but good information. Somewhat confusingly, you zoom in on the map not by hitting the zoom button, but by hitting the state or portion of the state that you want to view. For example Southern California. That will take you to the map for that area, which again does not zoom in. It does, however, highlight the nasty passes what you can then select and read the information on. Works well on a 10in tablet. It is 2015 information, but passes do not change that much.

Would be good if it gave the information I needed, but it was completely unsatisfactory for what I need. Refunded immediately after installation. Hope it's better for others... Sounds good but didn't deliver usable information for me.
