• 14.2 miles roundtrip.
• 4800 feet elevation gain (8,800 at the top).
• At least 2000 stairs.
• 2 majestic waterfalls.
• 3 pounds of trail mix.
• 10 painkillers consumed on the trail.
• 7 walking sticks picked up on the trail.
• Three knees in utter pain.
• 100 meters (or so) straight up a granite sheet.
• One really strong forearm muscle.
• Countless (truly) amazing views: towering redwoods, layered rock faces, snow-covered peaks, animals scrounging, hawks watching, green valleys below and a steady line of intrepid hikers above.
Yosemite is a true splendor and one of the most divinely natural places (even with all the humans) that I’ve ever been.
But the lesson was, perhaps, most important: Everyone has his or her limits, and we should know and respect them.
For those who haven’t been to Yosemite, or climbed Half Dome, or even heard of it, let me tell you. It’s not the 14 miles that are intimidating. It’s the ascent up to Sub Dome, which is about 300 meters up stone steps on the edge of a cliff, and then the 100 or so extra meters up the granite face with nothing but a couple of thick cables keeping you up there. (At that point the lesson was summed up as “Don’t look down.”)
It’s called Half Dome because it literally looks like someone took a dome and chopped half of it off vertically. The truly crazy people rock climb up the 90-degree face. The slightly less crazy use the cables to go up the “curved” side (in quotes because, honestly, there’s not much of a curve).

That's the view from the top of Sub Dome, looking with awe at Half Dome.
Amanda and I hiked with a friend from the DOJ, Nicolle, and her boyfriend, Alan. Along the way each of the four of us found our limits and stopped where we needed. So did the other hundred or so people we came across on Sub Dome and Half Dome. We decided that the reason there aren’t more accidents on Half Dome (and really, there aren’t that many) is because people self-select—they find their own limits and they listen to that inner voice. Some may call it chicken, but as the gentlemen who welcomed me back to horizontal ground at the bottom of the cables said, others will call it smart decision-making. Survival instincts.
Whatever you choose to call it, or however much you choose to push yourself, climbing Half Dome is an experience of a lifetime. I’ve done some really memorable hikes, and this one is right up there with the snowy slide down Pucón, the Chilean volcano, and crawling along Katahdin’s knife edge in a hail storm.
Here's the view from the night before, looking off of Glacier Point at the next day's adventure:
