Lighted Half-Dome

In order to raise awareness of themselves, and all the work they do, the American Safe Climbing Association, ASCA, climbed Yosemite’s Half-Dome at night and installed 39 solar-powered LED lanterns to trace their way up.  This was done to make the group known, and to let people know of their work, which mainly consists of replacing bolts on popular climbs.  They’ve replaced over 14,000 bolts over the last 18 years, that’s alot.  The awareness stunt worked, because I have A. never heard of them, B. never knew this was that big of a deal.  But, I’m not a mountain climber, so it’s not surprising to me.

Now, before you get all excited, these lights were only temporary.  The group removed them as they climbed back down.  On the reddit thread about it there’s a long discussion about that aspect.  I tend to agree with the unpopular post, I think this sets a dangerous precedence for future publicity stunts on our Nation’s National Parks.  Hopefully clear heads will prevail and Exxon-Mobile won’t be able to buy advertising space on the sides of mountains, not until they buy them outright that is.

Mountains Breaking Up

What would you think if you came across this scene while hiking?  The ground is not shaking, but cracking, and popping, but there’s no ground shaking like an earthquake.  What would you think is happening?  The ancient buried alien space craft from War of The Worlds would soon make it’s way out of the ground and zap you?  I don’t know, I’d be pretty freaked out to be honest.

What’s really going on here is the ground is expanding.  The lack of pressure is causing the bedrock to expand, since this is rock, it has to expand somewhere, so the rock cracks.  I think the coolest part that’s also the most scary is when the crack happens, and the dust pops up in the air, just like a movie.  Nature is strange isn’t it?
