Via NW ridge w/NorthBen, hoping to make a big ridge loop out of it and the good forecast never even seemed to be in place. Snowed pretty much all morning with pea soup up top. Mostly compact snow down low with ~6-10" of dry powder above 4k.

Nice, that's a good winter trip. Not a bad thing that you didn't have any summit views, lots of clear cuts to the South to look at

That's a nice route. How far could you drive after getting off I-90? Where is that view of McClellan over the river taken from?

Depends what you're driving. There's a snow berm built up just before the bridge over the S Fork, before the junction with Tinkham Road. Some people were able to get their jeeps etc over it (and several miles+ down Tinkham Rd) but most people were parking before it.

From the bridge over the S Fork. Best view we had all day lol.gif

Looks like a great winter destination! Which exit did you take off I90? I've been there in summer, taking Hanson Creek road. Is that where you parked? Thanks !

Great trip to a worthy peak. This is a good way to stay close to home but get away from the crowds.

We parked directly off exit 47, south side in between the on/off ramps and the bridge leading to Tinkham / Asahel Curtis Rd. GPS here.

I climbed Humpback in March 2018. Although the climb to the top takes a timbered ridge, making Humpback a good choice when avalanche conditions are high, you should watch out for wind-loading on the final slope below the summit. This slope slid on us, and carried 3 members of our party a few hundred feet down the slope. No one was injured, but we got lucky. Here's some photos:

Looking up at the crown on the right slide of the slope. It was about 2 feet thick.

good info, thanks for posting that, glad everyone's OK While ski touring we rarely dig full blown pits* but we do a lot of quick hand/pole pits as we move through changing terrain and conditions---especially as we approach ridge lines where snowpack and conditions can change quite rapidly and dramatically. *No point in digging a big pit when conditions can change dramatically within as short a distance as 50 ft.... although big pits have their time and place too ALSO - when moving across questionable terrain it's generally a good idea to space it out between folks. That way, if it does go, not everyone slides at once... good to leave a person or two standing in case excavation is required. wink.gif

Wouldn't have expected a slide like that on Humpback. This is worth its own thread for increased visibility.

^^^ I agree with JSH. Spent most of Friday & Saturday researching options for Sunday (mod-avy-day), with Humpback in my top three, but a few winter trip-reports I found talked about moderate-avy danger near summit but never really described where -or- in what way... and was hard to visualize on topo, these photos & report are exactly what I was trying to figure out...
