Here again you may want to consult your favorite fortune teller. March, November and even December can offer groupings of pleasant, excellent days for climbing. Falling Rock climbing area, outside of Rapid City on Hwy 44 is nice due to its sheltered and south facing rock. As climbers, we like to minimize our exposure to risks that we have no control over. Bad weather, rock fall, bee stings and bad drivers from states with no hilly roads are just some of the potential hazards that are best avoided when possible.
Weather presents many threats to climbers.
Rain is a serious issue here in the Black Hills since it turns the lichen on the rock into something similar to wet, waxed floors. The rock here is actually mostly white with red streaks. Sometimes, like on Devils Tower, you can see weather moving in long before it hits. Other areas and particular climbs do not present this option. Retreat off of a spire or cliff usually takes more time than one thinks.
