Sorting Books

Hey, if you’re reading this, honey, I am still working!

Hey, isn't that where Jon dropped Ed? (Neaderthal, 5.8)

Hey, isn’t that where Jon dropped Ed? (Neaderthal, 5.8)

I have a lot of boxes of books and CDs I am going through today because the house is supposed to look unpacked by tomorrow. Today, I got into the climbing books. I’m keeping just a handful because they’re special:

Self Rescue, because we took a self rescue course together at the PRG many years ago

Classic Rock Climbs of Ralph Stover Park, because that was my home crag for a lot of years. Even when I wasn’t climbing there, I was mountain biking or just hiking around because the scenery was beautiful.

129083844-High_ExposureCU_web_Finally, my Gunks Guide, because that was the real home crag in the Northeast and we did a great assent of High Exposure there that I think of quite often to this day (and thanks to Barry for going back to retrieve the cam that I thought would be part of the route forevermore). Oh, and it’s also the place where I got a concussion from hitting my head on Dave’s knee after falling off a bouldering problem and complained about the damned hippie music coming from the woods all night.

Other than that, I’m working and just have some climbing videos running in the background – you know, while I work.

(if you are not a fan of bolted routes, skip this one – but what a climb!)

(if you don’t want to be completely schooled by a 10yo, skip this one)

boy, I miss having hands!

More on Oxygen Binding

A reader brought up some interesting points and uncovered some details about Oxygen binding that I wanted to update. You can find the transcript of our discussion in the ‘Getting Oxygen Where It’s Needed’ post below.

What I wasn’t able to post there was a graph of an Oxygen dissociation curve comparing caucasians with Sherpas living at high altitude (+4000m) and those living at sea-level. Surprisingly, the advantage Sherpas have in binding Oxygen at low partial pressure is completely lost at sea level. (see below)


Oxygen dissociation curve of the blood of (A) Sherpa living at high altitude, (B) Caucasians, (C) Sherpas living at low altitudes.

Presumably,  caucasian blood came from those living at sea level. It would have been great to have data on caucasians (or anyone, else for that matter) living at both high and low altitudes.

For those unfamiliar with data presented in this way, the horizontal axis starts at very low Oxygen concentration on the left and increases to the right. The vertical axis shows the amount of the subjects’ blood binding oxygen at each particular concentration. If the curve rises quickly on the left side, it means that the blood is picking up Oxygen even when it is present at relatively low concentrations in the air.


Data from:

Sherpas living permanently at high altitutde: a new pattern of adaptation.
