What’s new at Backpackinglight?

Lightning

  • Introduction – Anecdotes from Long’s Peak, Rocky Mountain National Park and the Wind River Range
  • What is lightning?
  • The seasonality of lightning – June, July, and August in the Mountain West; wider windows in the Midwest and Southeast.
  • Mechanisms of injury – ground current, side flashes, contact, upward leaders, and direct strikes
  • Pathophysiology – electrical shock, secondary heat production, and explosive force
  • First aid for lightning strikes – Scene Safety & Basic Life Support, if multiple victims triage, then assess, monitor, and evacuate.
  • Risk Mitigation – avoid travel through passes, peaks, and ridges when storms are nearby; in many situations this is before noon.
  • Other risk management tools – flash bang rating system, the 30/30 rule, terrain and environmental features
  • Regardless of where you are, executing the crouch position on a foam pad is the best thing you can do in a lightning storm.
  • When you can sense the corona of a lightning bolt, then you are at extreme risk of being injured by a lightning strike.

    In regards to the filmed corona event posted by David earlier:

    Why is the narrator stopping every few minutes to take her own selfie video while narrating how bad things are getting? Don’t do this!! I was with several others at the top of an exposed pass when lightning was striking  immediately around us. Everyone raced as fast as possible down towards treeline two miles below. No one stopped to record selfie videos describing their  situation. Are you kidding me?

    Looking at Dixie’s video again, I’ve had that same experience, many years ago in Denali. The lightning was far off, the storm miles away. Nevertheless when our hair started to stand on end, we descended as fast as we could. We were in open terrain for at least an hour before getting to trees. Where would Dixie have descended to up there? It’s miles and miles to get to below treeline.

    When we were going up Muir Pass a few years ago, we were about 1/2 mile from the shelter when a thunderstorm rolled in, without clouds or forecast or anything. Just suddenly appeared over the crest of the hill. Do we then go up or down in all those rocks? Treeline a long ways away on the side we came from, so do we keep climbing to get down on the other side, where the trees are closer? “Run” to the hut? (I couldn’t have run, so it doesn’t matter.) Sometimes the answers are not clear. You do your best, and hope for the best. Or stay home and watch the video and never go.
