long slog via 8040/CS versus 8020/lava flows?

Must agree with others, and add: Doing Adams in May ever, but especially this May, is going out of your way to needlessly suffer. There are a ton of better options, which is why the PNW is awesome.

I'm pretty sure Whittaker didn't think Super Yeti was afraid of work when they summitted Rainier last year, but maybe he's just really polite.

Well, with 2 weeks and flexibility as to when you buy the ticket you stand a great chance of hitting a nice weather window, so ultimately you'd be pretty likely to succeed however you did it.  I don't know what other plans/obligations you might have with family or friends but in that amount of time you could get a lot more done than just Adams.  You could also consider doing Adams towards the end of your trip as hot weather could clear at least a few miles of the road while you ski St. Helens, Muir, Baker or whatever else.  Maybe that way you shave a day off the approach, time you could use to ski something else or just to hang out.

Do reconsider camping lower and skiing with a lighter pack.  It's just a better way to go if you're skiing the chutes.  Traverse back and grab your stuff on the way out.  A lower camp will also be warmer, less windy, and there may even be running water, which would save you a lot of time over melting snow.

Also reconsider renting some AT stuff.  I did it for my brother when I was first getting into it (first trip was Adams S rib by coincidence), it's really not that expensive, would save a lot of weight, and give you the option to skin, which would end up being very helpful for traversing back to your camp/car.  It will be real hard to keep the weight down if you are carrying alpine gear + climbing boots.  Huge weight savings are possible there.

Great local source for weather forecasts on the PNW: wowweather.com/ Mike will give you custom forecasts -- he can also sent you updates in the field via TXT on cell or sat phones.

In terms of haulling a full pack up high -- seems like you are trying to prove something to yourself more than anything else -- a lower risk approach to testing your strength would be to find a hill locally and start climbing laps on that with your heavy pack -- 12 laps on a 500ft hill is still 6000 vft -- if you are restricted to using a stairmaster for your training -- be sure to start wearing your pack for that as well -- it's not just the legs that need to be strong.

Brian,

I've skied the chutes from both Morrison Cr and Cold Springs. I have some old TOPO files I might be able to convert to a GPX file to import into your GPS if you have one for this trip. If your interested PM me. For your trip I don't recommenced going up from Morrison as connecting up with the south climb route above timberline is more difficult, Start at Cold Springs no matter how you get there.... (the road will still be snowed in). I highly recommend camping at timberline elevation not the lunch counter. There is a waypoint in my file called "bivy" which is ideal for this. My file has waypoints for the false summit, lunch counter, CS campground, etc. ...could be useful if caught in a whiteout.
I can't remember if you said were looking to ski the SW Chutes... Regarding skiing the chutes. When its over, there is an obvious notch in the terrain skiers left to aim for to begin the traverse back to the south climb route. I have a waypoint for that too. Anyski mentioned the south climb route is underrated and he is right, its a fun ski and may be a better option for your adventure...
My advice is rent some AT Gear, full skins and ski crampons. I hope you get a bluebird weekend... keep an eye on the weather and forecast. I look forward to the trip report.

Oh my gosh. There is soooooo much bickering on this forum. You say you are listening to others, but are being very arrogant in your replies to advice others have. Hey, more power to you if you can pull off the trip solo in questionable conditions, just make sure to at least tell somebody your route you plan on so the park rangers can retrieve you when you fuck up (excuse my language) It just pisses me off that you feel like you know everything about the mountains here and seem to have a complete disrespect for them. THEY WILL DICTATE WHEN YOU CLIMB AND WHEN YOU WAIT. Thats my two cents.
