Tidal volume is the volume of air inhaled/exhaled in a normal resting breath (about 500ml). Yep the pressure differential is what draws the air in and expels it when you exhale. Totally dependent on the volume change in the thoracic cavity when your diaphragm contracts/relaxes. Thanks everybody. I feel prepared now. Time to drink in a couple hours. Yippee!

Yep, presicesly what I said Erik. Fewer molecules per volume 'X' (liter, gallon, cubic foot). Ratios in the volume remain constant for the balance thing, still 20% O2, but the fewer molecules = less O2 delivery on each breath... Thus the need to acclimate.

Yeah that's a set maximum, but does tidal volume remain relatively constant?

Sorry in advance for posting this in the climbers forum, but I figure it is more likely to be seen by someone with an answer to my physics question...studying for a physiology exam tomorrow. We all know that at higher elevations there is less atmospheric pressure, meaning less molecules per volume X. At sea level the difference during normal breathing between the pressure outside and inside the lungs is about 1mmHg. This is one component that helps with normal inhalation. Does this relationship hold at altitude? [i know there is less O2 and understand what the body's response is to compensate, so no need to comment on that.] What I am wondering is if in general the same volume of air (not compostion) is being inhaled at altitude. Thanks for your help.

"Lord of the Ring" and "Boardman-Tasker Omnibus" Just finished "A Woman of Independent Means". Not that many of you hardmen would enjoy it, but there are a few other chicks on this board. A nice fictional read about a pretty progressive woman who lived from late 1800s to the 1960s. Told entirely through letters she wrote to other people in her life. Kinda unique style.

Thanks for the TR Timm@y and for the challenge to remember. I needed that today.

Simple Green and HOT water. If they need lubed use one of the teflon based products like Cam Lube. Feathered Friends carries it.

Yep. Pretty lame if you ask me. (not necessarily the party, but the organizers current behavior...)

As soon as I get the all clear on the shoulder. Gotta keep it at 5.easy for a while.

no prob... Interesting mental image.

you've got that fashion stuff wired iaxx

Sorry I can't speak to this year, but I climbed it in late June 2 years ago and there was nearly constant rockfall from the summit rocks once the sun hit and we were punching through snow bridges like crazy. Nice climb but not sure I'd do it this late. You may have to traverse far to the left to avoid the big crevasse/shrund that forms every year. We had to do this as the headwall looked sketchy. If you go this way get and early start. You'll probably have that whole side of the peak to yourself which is one good reason for checking out that route. We only saw other people when we got up to the football field below the summit and the hordes from the Easton were coming up behind us.

Cool TR MisterE. I like to sit in the parking lot and get a good view of the upper pitches on LTW. Was this your TR to start with?

Long day but doable with a light pack. Traverse Forbidden East to West. Might end up finishing the hike out in the dark if you have traffic on the West rigde downclimbing

Prop 13 is one of the problems, but the state gov't can still raise property taxes 2%/year. It was passed because the state was getting out of control in levying property taxes back in the 70s. Yeah it has put their public education system in the toilet, but the real problem was the power crisis a few years ago. The Gov and other politicians were paranoid that if the state could not promise reliable power and eliminate the brown outs that silicon valley, food processing and other industries would simply walk out of the state. Then they got fked by Enron and a few other companies.

This totally sucks. You used to be able to find the aid gear on Conrad Anker's site and I had heard a rumor that he bought that portion of A5 from TNF, but they kept the bouldering clothing line. There is no info now and the link takes you to the stupid bouldering clothes. IMO the whole extension to bouldering clothing from a tried and true aid brand is another classic mistake of that f'ing company and their marketing VP who "made Columbia a success". What were they thinking?

Jon - check out the flick "13 Conversations About One Thing" if you haven't seen it. All moments that changed those people's lives.

Actually trask, I thought that hippies are into The Dead and similar tunes, wear dumpy looking clothes, and are into free love and all that.

And for getting yerself a matching pair. I feel so cool.

So in another post people are equating dirtbags with hippies. Discuss. Personally I define dirtbag climbers as people who climb as much as they can, are comfortable living out of their vehicles, don't need to shower, shave, etc. as often as the average non-dirtbag, likes to figure out how to work the systems for free or near free stuff, likes to have a good time.

Good luck with that Rob. You may make a killing. I figure I'll just laugh at myself if I decide I don't like it. And when I'm 80, it'll be even funnier.

You gotta come up with your own idea. Sometimes it takes years for it to gel...at least mine did.

Thanks for reminding us Erik. It's all a fog after the last bash.

There's a great trail out of Gold Bar at Wallace Falls. The whole thing may be a bit much for a 5-year old. But the first couple miles are nice wide trail through the forest, few roots and rocks. You could bring a long a cable lock and hitch your bikes to a tree and walk down to the base of the falls on that trail (no bikes allowed) or continue up to the point where it hgets pretty rocky and he may to walk his bike.

Beck - I didn't mean to start a big debate on the Rope Up. I think you are taking some people's comments too personally. You did have the idea for a climbers gathering back in 2001 when pub club got started. I think we began doing organization for that late Sep event in late August. Lot's of us who are speaking up about grass roots organization helped out with the event. It seems like you think this is your event and a little acknowledgement of others who have been involved from the get-go would be nice. We all brought beer, shared food, and most importantly had a great time. I think there were 20-30 people that showed up. Last year the shin dig was in Oct and I don't recall that a lot of planning other than posting a date and someone from Oregon (I think Tex and JK) agreeing to bring a tap and pick up TG's keg. We had over 40 people last Oct. and it was a blast! This year we started talking about a date in the spring so people could do some planning for their schedules. There was a pretty big debate about which weekend and somehow it got resolved and the date was chosen. I haven't heard/seen any requests for assistance with planning and had just started to think that we should get stuff underway since it's almost August. Then I get the notice about the event from the AAC. No big deal, but I wouldn't have minded a little group brainstorming or helping you with organization. I guess I'll have more time on my hands and just show up and see how it all turns out.
