It's an old rating scale-
I first heard it back in the 80's in Camp 4- guessing it was started by climbers- probably alpine climbers.
I recall posting it here on the forums a few yrs ago-
The understated implications are:
Level 1: No one hurt but it could have happened- just some inconvenience and a little hardship.
Level 2: No one's hurt bad or it's minor- but one notch farther and someone loses a limb or life- a some what close call- a standard Epic if the story last longer than a whole day.
Level 3: Someone dies or is badly mangled- it's really bad for lots of people who were not even there.
All the levels generally only apply to doing really cool stuff.
Context: Probably goes back the Yosemite 60's days when the Bridwwell Aid ratings on big walls were -for a short while anyway –
NBD – No Big Deal = A-1-2
PDH- Pretty Damn Hard = A 3-4-
RHU- Real Heads Up = A 4-5
You get the idea- but Level 1 is not just a reg fun day out in the woods- that is somewhere below Level 1…
