I believe Pipeline is at least 45 degrees, and is supposedly 50+.
yeah I have its looks alot harder and gnarly than it really it is. The top is still on a hanging snow field but its not steep.
Great Scott, High Rustler, nirvana, eddies, and various other inbounds runs are all steeper.
I would admit you have better chance of dieing on pipeline, but once your in the chute its a wide open easy run.
andrew mclean rates it at a S4 + which is for sure fall or die terrain untill you get into the chute. Its not 45 degrees though no way no how.
S0 ..... Flat terrain. A golf course.
S1 ..... Low angle. Possibly poling in places.
S1+ ... Beginning terrain at a ski area. Safe run-outs.
S2 ......25° slopes. “Intermediate” terrain at a ski area.
S2+ ... Slopes at or near 25° with some terrain features.
S3- .... Slopes up to 30°.
S3 ..... Slopes up to 35°. “Expert” runs at ski areas.
S3+ ... Slopes at or near 35° with terrain features that require maneuvering around.
S4- .... Slopes 35–45° with safe run-outs and little to no dangerous terrain features.
S4 ..... Slopes 35–45° with dangerous fall potential and a few terrain obstacles.
S4+.... Slopes just under 45° that are continuously steep, have serious fall consequences and multiple terrain obstacles.
S5- ... Slopes that are continuously at or near 45° or slightly over.
S5 .... Slopes between 45–55°. You’d be lucky to live through a fall.
S5+ .. Slopes at or around 55°. Falling est verboten.
S6- ... Short sections that are steeper than 55°. Most of the run is continuously above 50°.
S6 .... Slopes continuously steeper than 55°. Painful death from falling highly likely.
S6+ .. 55°ish slopes with major obstacles – cliffs, trees, crevasses.
S7 .... 60° slopes. Just plain ol’ steep as hell.
S7+ .. 60° slopes with nasty obstacles. A quick and certain death if you fall.
S8 .... The future.
I have never done anything from his book over S5 but I will admit outside of ski area boundraies I am wimp. I know skifishbum has done those andrew list in his book and more.
