Booting up towards the ice. Spacial awareness is important here, as well as with chirality. |
****WARNING: science alert. Skip down if you aren't interested, the photos are good.*****
In organic chemistry, one of the hardest concepts to understand includes something called chirality. Now hold on, before you go look at cat videos, lets give this concept a shot. This is hard to explain in words, but is usually visualized better by look at photos. Make sure to check out the ones below. However, more or less, the concept is basically that you can have different kinds of the same molecule depending on how all of the atoms are bonded in relation to each other. A subpart of this idea is something called enantiomers (a big word, stick with me here). Enantiomers are mirror image molecules that are not superimposable; a good example of this is your hands. They are mirror images, but you cannot slide one on top of each other and make it match, your thumbs stick out on either side. Got it?

Don't get worried about the names, the idea is to see how they are mirror images. The blue atom in front and on the right
is now the blue atom in front and on the left. they all have switched positions relative to each other.

It is hard to see how it all applies. With this photo, you can see how those specific
spacial arrangements matter for the binding sites that are so specific.

Now that we have an idea of enantiomers, we can look at biological molecules. Chirality is important in biochemistry since molecules form 3D structures in space and each enantiomer has a unique shape, even while being the same chemical. Weird right? This becomes important because each protein in your body has a specific spot that it will bind with other molecules, and it has a unique shape. So often times, only one enantiomer will work, while the other just will not fit; just like a lock and key.
Advil or ibuprofen is a cool chemical. The ibuprofen you buy comes in a 50/50 mixture of both enantiomers (mirror image molecules), and only one of the them is biologically active. What you say, I purchased the whole bottle and only half of it works!? No, what is interesting about ibuprofen, is that your body will change the inactive version into the other active version when it starts running out. Pretty rad. Cocaine on the other hand is different. When synthesized by humans (natural pure cocaine is the 100% biologically active enantiomer) it comes in a 50/50 mix just like ibuprofen. What is interesting about cocaine however, is that your body cannot change the inactive enantiomer to another. So you do only get half the active amount.
Why is this relevant? Well, I feel like climbing is more like ibuprofen than cocaine. Climbing is such an undefined sport with countless facets, that whatever you are psyched on, we can find something for you. We can always change our "climbing enantiomer" to another we need or want. When the ice is good, go ice climbing! When it is not (in Utah the weather likes to keep you on your toes) just go rock climbing! Different styles, different areas, different people, it is never old, if you don't want it to be.
Ice Climbing

The Donercicle in WI6 mode. One of my favorite pillars. |

Matt is strong, I am pretty sure it is because his tools and crampon colors match.... |
 |
You have to love CCC falls. I only wish there was a way to
have a mixed route to the right without drilling. |
Rock Climbing
 |
The worst part of having so much gear, is deciding if we should take it? |
 |
If only there was more ice on the river, we could have walked
there instead of bushwhacking. |

What a beautiful place. Even with the La Sals obscured by
clouds in the background, there is an immensity to the area. |
