This book provides the locations and descriptions of over 400 mountain passes and steep grades in 11 western states. This information is vital to anyone driving a large or heavy vehicle. There are 12 full color relief maps showing mountain ranges, valleys, cities, highways, etc. Text details include how long and how steep (%) the grades are, whether the road is two, three, or four lane, if there are sharp curves, switchbacks, escape ramps, narrow shoulders, etc. Many mountain grades are hazardous to large or heavy vehicles and knowing what lies ahead can be life saving. Grades can be too long and steep to climb and descend safely. If you've ever had the terrifying experience of losing your brakes while descending a mountain, you know it is not something you want to repeat. Remember the old phrase, 'You can go down a mountain a thousand times too slowly, but only once too fast.' Some roads are so narrow and winding that large vehicles can't stay in their own lane on the curves. This is hazardous for everyone on the road and in most cases, can be avoided by choosing a safer route. There is a companion book, 'Mountain Directory East' that includes the locations and descriptions of over 300 mountain passes and steep grades in 11 eastern states. There are many more hazardous grades in the east than many people realize. While 6 and 7% grades are common in the west, 9 and 10% grades are common in the east and the roads tend to be more narrow and winding in the east due to age and terrain. Many escape ramps are completely inadequate. These books are extremely valuable references for anyone driving a large or heavy vehicle for work or pleasure.
