I’m torn on this one. On the one hand, it’s a really cool device that cheaper & lighter than a real sighting inclinometer.

On the other hand, I pity the forecasters who now have to deal with EVEN MORE morons who ski 37-degree slopes when the hazard is high on 38-degree slopes, get buried, then whine that the forecast was faulty :|

Andrew McLean’s Steep-Speak International Translations:

France:
Subtract 5 degrees & 1/3 of the stated vertical, e.g. 1000 meters of 50 degrees = 660m of 45 degrees.

Alaska Heliskiing:
Subtract 20 degrees and cut the vertical in half, e.g., FIVE THOUSAND FUGGIN’ FEET OF 60 DEGREES (Dude!) = 2,500′ of 40 degrees.

Montana & Washington:
Accept at stated values.

California:
Subtract 10 degrees, nip the vert by 1/4 and double the width of any stated couloir.

Oregon
There is no steep skiing in Oregon.
[jss note: I suspect this reflects the lower half of the state's sharp divide between low-angle clearcuts with tele skiers falling all over the place and super-gnar technical ski mountaineering routes, with not much in between]

The East Coast:
Overstated stats, but the conditions justify it. Accept at stated value.

Colorado:
Whatever Lou said it was.

Utah:
I’ll take the 5th on that.

Film/Movies:
Cut stated angles and length in half.
