 ## Matthes Crest
 One of my earliest climbing experiences was on Matthes Crest in the spectacular high country between Tuolumne Meadows and above Yosemite Valley.

-Unfortunately, our traverse of this magnificent route was cut short when I fell a very small distance landing on my back on some rocks. It knocked the wind out of me, and I bruised my ribs bad enough that it was hard to breathe. I was so embarrased that I couldn't stop laughing which was also painful. What happened? Why did I fall on such an easy route? I think I can chalk this up to a combinaton of unknown risk, inexperience, carelessness, and hubris. I had never climbed outdoors before, and falling wasn't my only mistake on this route. I also lost my belay device which fell off my locking caribeener which either wasn't locked or somehow unscrewed itself. There wasn't a lot of exposure where I fell, but I failed to evaluate the risk and decided on a risky boulder move, without considering the consequences. I was clearly careless, and I think I was overconfident. The rock is merciless and quick to deal out stern lessons whether you have the aptitude to learn from them or not.

 ## Sons of Yesterday + Serrenity Cracks
 The most terrifying fall I ever had was on the rappel between Sons of Yesterday and Serenity Cracks. A similar incident was reported in this article in [Climbing Magazine: "Five Preventable Yosemite Climbing Accidents"](https://www.climbing.com/skills/analysis-five-yosemite-climbing-accidents/):
