Hiking Half Dome

We've been waiting for this hike for several months now, having secured our permits early in June. Matt had hiked Half Dome before, so he wisely advised me not to bring my big bulky DSLR in favor of his smaller (and much lighter) point and shoot. He also advised taking as much water as I could carry (we each carried 64 oz, but could have used more), and reassured me that the cables at the top of Half Dome were not that steep.

We woke up at 5:15am on the day of the hike, drove to the valley, and parked about a mile from the trailhead. We officially started hiking at 6:30am, following the Merced River upstream. The first 2.5 miles were steep and packed with tall stairs made of huge chunks of granite.

The first major milestone was Vernal Falls, a beautiful (and deadly) 317 ft waterfall spilling out over sheer granite cliffs.

Since the sun hadn't risen yet when we started hiking, we were treated to glimpses of golden morning light as the sun rose. It was also nice to get a couple of solid hours of hiking without worrying about sun exposure. The morning was cool and breezy and perfect weather for hiking.

About 2.5 miles into the hike, we reached another milestone, Nevada Falls. We decided to take a break here, having a snack and a water break to breathtaking views.

From here, the trail flattened out for a mile or two, a welcome break from steep stairs. We passed Little Yosemite Valley, a backpacking camp for those who choose to do Half Dome in two days, and then a Ranger Station. Soon after that, the trail began to steepen again, and it remained at a pretty constant grade for the rest of the way to the Sub Dome. I didn't take many pictures for this part, mostly because I was battling the altitude for breath as we climbed higher, but suffice it to say, the forest was beautiful. Yellow pines and the occasional redwood leant some much-needed shade to the trail.

We reached the Sub Dome by 10:45am. This last segment before reaching the cables looks incredibly steep and rather daunting as you approach it from the south. But at this point, there's no turning back. We climbed the Sub Dome slowly, and finally made it to the base of the cables around 11:30am where we took a break for lunch before attempting the steepest section of the hike.

After lunch and a rest in the only shady spot on the Sub Dome, Matt and I prepared for the cables. I was terrified, to put it lightly. Matt had assured me on the way up that the cables wouldn't be that steep, but it turns out that his memory was not quite as accurate as he thought. In fact, the cables are the steepest part of the entire hike, going just about as close to vertical as you can get. Without the cables and little bits of wood to hang on to, there's no way Half Dome would be even remotely climbable. As an ominous example of what would happen if you fell, while eating lunch we watched as an empty Nalgene bottle fell out of a climber's back pack at the top of the cables. It tumbled down end-over-end in a free-fall, bouncing off the rock face for a good 30 seconds before finally coming to rest on a tiny ledge at the base of the cables. Not the most reassuring thing I could have witnessed at that moment.

But Matt wasn't going to let me go all that way and not get to the top. So we put on our leather gloves, I swallowed my fears, and we started the ascent. The climb was intense, to say the least. To pull ourselves up the cables required not only leg strength, but core and arm strength as well. To complicate matters, other climbers were coming down as we were coming up, so passing people takes some bravery (as does looking down).

Finally, after a lot of hard work we made it to the top around 12:30pm! The views were stunning, and as everyone says, well worth any sweat and pain it took to get there.

We conquered Half Dome!


Views of the valley behind us - compare this view with the one from the top of the Sub Dome. You can see the forest that was previously in the foreground is now quite a ways beneath us now.


After summiting, we began the long journey back down the mountain, beginning with descending the cables. I was not looking forward to this part, but Matt went first, and we both hung on tight. After that, we made good time on the way back down, stopping periodically to enjoy the views again from the other direction.

We ended the hike around 5pm, making the total hike roughly 4,800 ft elevation gain, 17 miles, and about 10.5 hours. Not too bad! Although our feet and knees didn't thank us for the trip, it was an awesome day and one that I won't ever forget. We might even be crazy enough to do it again next year!

Yosemite Weekend

This past weekend Stacey and I headed to Yosemite to climb Half Dome. We woke up early on Saturday for the long drive east, set up camp at Crane Flat, then went out to explore in the remaining daylight.  We drove up along Tioga Pass and enjoyed many scenic views along the way:

This was our first stop: you can see Half Dome way off in the distance here.

The view just southwest of Tenaya Lake, watching thunderstorms roll over the landscape.

We reached Tuolumne Meadow just ahead of a big thunderstorm.  Luckily we had enough time to explore a little and snap a few photos:

There's a bit of snow up in these higher elevations

Next we decided to check out Mono Lake, which is just outside the eastern gate of the park.  We wound our way down a steep ravine with a killer view:
Losing altitude fast

There were lots of cool natural rock formations

And some cool not-so-natural ones (this is a blast hole from dynamite used to make the roadway)

Mono Lake was a surreal experience; the sky opened up and the landscape went from rocky and mountainous to almost completely flat.  Strange spires of rock jutted out from the lake, and the air smelled like sulphur.  We walked out along the boardwalk to get a better look:

On Sunday morning, we woke up early again and headed for the valley to explore.  The early light was great for photos, and the valley was relatively deserted:

Our next stop was the Ahwanee Hotel for an luxurious brunch, then we drove up to Glacier Point to mingle with the other tourists and get some famous views of the valley:

One of many staggering views of the valley from Glacier Point.  Even with overcast skies, the scenery doesn't disappoint.


Next up: hiking Half Dome!  In the meantime, all of our photos from the trip can be found here.

Water Carbonator!!

Ok, so Stacey and I drink a lot of fizzy water. Normally with a lime or two squeezed in. Delicious. But, that means that we buy cans of club soda from Safeway allll the time. I've been toying with the idea of building my own water carbonating contraption for a while, but I've been a bit too lazy. Until now!!!!

Parts:
  • 5lb CO2 tank from beer supply store
  • Dual gage CO2 regulator from beer supply store (one gage tells you how full the tank is, the other one sets the output pressure)
  • 5/16" beverage tubing from beer supply store
  • Locking ball air chuck from auto supply store
  • Barb fitting to attach air chuck to tubing
  • Hose clamps



Ok, so put all that together and you have the carbonator, but you still need a way to get the CO2 into the bottle and keep it there.

I built some valved caps by taking the cap off of a 1 liter soda bottle, drilling a hole in the top, and then installing a valve stem from the auto parts store.

Parts:
  • Screw on soda bottle cap
  • Valve stem




How to use it:
  1. Chill water (cold water absorbs more CO2)
  2. Squeeze air out of bottle, tighten cap (this makes more room for CO2)
  3. Attach locking air chuck
  4. Set regulator to ~45psi
  5. Open regulator valve
  6. Shake for ~20 seconds. As you shake, you'll hear more CO2 flowing from the regulator as the CO2 is absorbed into the water. Once it stops flowing, you're done.
  7. Enjoy!!! Or store in the fridge for later.

Once the CO2 runs out (in a year, maybe...) it can be refilled for $10-$20 at beer supply or welding supply store.
