It's not a simple answer. And there is a lot that is inferred from what you wrote
about what nps said. What I would get out of what nps said is that it's not enough
snow and danger that you probably won't need an ice axe and you probably
can simple post hole up the NORTH side of the pass... and the SOUTH side
is probably free of snow. Post holing gives you a lot of stability... so that is
why you MAY want to create your own. BUT it depends on how deep the old
postholes are... what the current state of the snow is... and IF you can posthole...
and IF when you posthole do you have a crust layer on top that is ripping
your legs on the penetration.
SOOOO... all that being said... in a normal year... typically you may not
posthole at all or very little and simply walk on top of the snow... but since
we've had such a goofy year... you may end up postholing quite a bit...
This can be VERY tiresome... but doable as nps said.
As for seeing/following the trail probably others have been thru and hopefully
followed the trail and it should be obvious... even with that much snow
there more than likely will be a depression where it settles and melts a bit more.
Unfortunately it can also hold there where it is gone everywhere else...
If it was a LOT of snow ... then an ice axe is in order.
Sorry, but I have only been up the pass once... it was october and it had
just snowed...
here's the trail from the pass looking east on the north side:
and the other side:
I would take solice in that the south side it sounds like is free of snow and start up from Rae
and just see how you are doing... if you are not comfortable.. then just hike back down and go back
out Woods.
Hope this helps.
Have fun and be safe
