Determining Mountain CharacteristicsBefore we can propose rules on how to climb a mountain in D&D, we must first establish guidelines that describe the mountain itself. As the goal with climbing is to cover distance, and because the distance is a less important obstacle than the difficulty of the climb, I have chosen to divide the trek into periods of time. The mountain is therefore measured in terms of how many hours it requires to complete the climb. An easy climb might enable a party to climb a thousand vertical feet in an hour; whereas a hazardous climb might enable only 45 to 60 feet in the same amount of time.
Each hour then describes a "slope line" ~ which describes a path of ascent between one point and the next, requiring one hour for a typical mountain climber to complete.
The number of hours that any given mountain might require would be determined by two factors: vertical height and type of mountain. Both can be decided ahead of time by the DM, then compared with one another upon a Slope Line Table that will give the number of slope lines for any given fictional mountain.
