Mokelumne Electra Run - 7/3/10

In anticipation of my packrafting trip to Alaska, I took a float down the Mokelumne River near the town of Jackson, CA. I was alone so I found a group floating in inflatable canoes to run with me. I gaged that this would increase my safety in case I went for a swim. After about the first half mile, I didn't see them until the takeout! Bastards!


Put in: right below Electra Powerhouse
Take out: CA-Rt. 49 bridge
Flow: 1800 CFS (high)
Approx. River Miles: 3
Air Temperature: 85F
Water Temperature: 58F

The run was really fast, and the waves were big -- the biggest I've seen in my Alpacka Denali Llama raft. There were myriad strainers, many times above the main current which piled against the banks of the river. Anticipation and backpaddling kept me out of all but one. I definitely felt at some point that the river was running me; but this is always the case...

One near-swim occurred at the S-Turn (mile 2.6) where the water piles up against the rock and wanted to yank the right side of my raft underwater. It was a sucking, tugging feeling, and ultimately I braced myself and two paddles brought me through.

Overall, the "Moke" was an ideal practice run for getting colder and bigger (versus Cache Creek near Rumsey, CA).

Notes on Technique & Gear:
  • I found that turning up the 'rpm' of my paddling increased my stability inside the rapids (versus 'ruddering' with a stationary paddle). It also, by virtue of the motion, brings your center of mass forward and towards the center of the boat, which also helps stability.
  • My GoLite Pinnacle backpack was stuffed with a surplus of water to simulate heaviness at the front of my raft (in lieu of unnecessarily jeopardizing equipment by stuffing it with clothes or other valuables) -- which made it slide down the raft and 'pool' on the deck. I will have to work to balance and secure it tightly at the beginning of the day, while also keeping certain supplies available quickly (TP, water, snacks). Overall, stability felt great with the extra weight up front.
  • My throw-rope was strapped to 'guard rail' directly behind my back. I find this position impossible to access in-boat, and difficult even while out-of-boat. I think a better spot will be within the pack-tach system right in front of me, quick-draw style.
  • I did not wear sunglasses, which improved my ability to discern the rapids and did not jeopardize a valuable (lost two pairs in rivers already!). Also, they get wet with splashing and perspiration that further degrades visibility on the water. I will consider installing a removable visor that will be nice on sunny, exposed days.

(note: I got out prematurely at mile 2.9, so missed "Devil's Toiletbowl"...the Class III. Will have to check this out next time)

To round out the weekend, I floated Cache Creek the following morning for fun. It was a quick float from the confluence of Bear Creek to Middle Campground at ~800 CFS. I hit plenty of rocks with my butt, but did not swim. My brother Bryant and his girlfriend Paige were there to greet me upon take-out. We took a few photos because well, it's Independence Day -- and it's good to be alive!

Mt. Lyell & Mt. McClure Summit via Lyell Canyon (6/25 - 6/27/10)

“ARE YOU HEADED up the chimney?” the climber bellowed from 300 feet below me, his voice damply echoing up the white fifty degree slope. Strike-two?

Strike-one had been the East Arête, a narrow, exposed ridge running up to the summit that was supposedly the easiest route to the summit – a straightforward “Class 3 scramble”, said the guidebook. No biggie. So I headed that way, doing ‘20-20s’ – twenty steps up, twenty breaths break; alternating water, organic gummy bears, and bites of a blueberry Clif bar. Feed the monster!...as they say.


Finally popping off the snowy slope and onto rocky land, I felt great. Now I had solid rock to climb, and was only a short distance from the summit. My fellow climbers of the Bay Area Mountaineering group looked like small, marching ants below. As I looked, though, they appeared to be heading up to the west side (!!). Interesting, I thought, but what did they know? Regardless, I popped off my crampons, gloves, and secured my ice axe to my backpack in preparation for ‘rock mode’. It was a slow, methodical process, keeping everything either attached to me, in my hand, or inside a pocket. A drop at this point would mean watching my precious gear tumble down down down – stopping, if ever, somewhere far below.

Feeling the sun-warmed rock in my hands, I peaked over the ridge and boom! – a sheer cliff, dropping off hundreds of feet down the south side. It was almost eerie, the stillness. The blue sky above and zero wind, high up in the air, made me feel calm, and alone. The granite cliffs of the mountain were torn, pounded, and honed by the Lyell glacier, leaving a narrow spine to my right as the only option to the summit – the east arête. At this point, it looked like a perilous route. Nonetheless, I started to climb.

Feature -- Arête (syn. comb, knife-edged ridge)
How to Identify -- Steep, sharp rock ridge between adjacent cirques
Probable Origin -- Quarrying by glacier in cirque

The moves were not difficult, but required both hands and feet, and a deliberate, defensive progression. Any gust of wind could toss me right off the ridge. I edged up, but each move beget a more difficult move, and now I was beginning to get high above a cliff on the north side too. Now I had cliffs dropping down on both sides, with a five foot boulder-strewn spine to the summit. Frankly, this did not seem like a great idea. Suddenly, I stopped and reassessed, a boulder wedged between my legs, my arms wrapped around it in embrace. I took a few deep, thin breaths – I did not sign up for this! With decision in hand, I downclimbed my tracks as carefully as I had come.
Strike-one.

Crampons on, ice axe out, I began traversing my way across to where I had seen the others head. That’s when the climber below brought up The Chimney.

“What’s the chimney?” I responded, with interest. “It’s a class 3 with one class 4 move.” Uh, okay. So, according to the guidebook, more difficult than the east arête? Not exactly what I’d like, but purportedly only one class 4 move? – I better check it out.

The chimney, I found, was a narrow vertical passage on the north face, shielded by rock pillars on both sides, and almost directly beneath the summit. Because it was kept out of the sun, it was the highest point the glacier could reach its icy tentacles. If I could make it up the chimney, though, it was save me a slog of a traverse to the west side, and who knows what that side would be like? So I started up again, letting the midday shadows of the chimney fold over me, the slope getting steeper yet. Almost to the rock-snow interface, the seam of terrain that denotes summit attack, I felt hard ice below. Getting adequate purchase with my ice axe was became more difficult, as it appeared the glacier was covered by only 3 or 4 inches of softer snow. Methodically switching to ‘rock-mode’ again, I shouldered my pack and started climbing -- this time up instead of over, and shielded. I hoped there would be access to the summit.

The rock was a mix of shale-like crumbly crap, and the silky-smooth-solid Yosemite granite. Each handhold had to be tested, some crumbling into a rockslide, others barely holding secure. I never once put all my eggs in one basket, so to speak, or all my weight on one hold. Without a rope, or obvious route, it was trial and error at its finest. Ten minutes later I was perched awkwardly on a vertical column of shale, and glanced up. It looked like a scramble above – aka an easy climb, if I could just get to the other side of the chimney, and make a shimmey around this column. It was.

I made a few moves that got me where I wanted to go, with gravel dripping down at each movement, and me slapping rocks to test, every once in a while squeezing my backpack through an opening as my ice axe scraped the rock. Onto the boulder, scree field above, it was a veritable hop, skip and jump to the summit. And I was there! Now with the west side visible, I could see the rest of the group a mere 100 yards below ascending the west side. “WOooO-hOooOO!”, it felt great!


After some photos and hangout time, four of us (Gary, Frank, Adam and I) headed west to summit Mt. McClure (12,960') which included another ‘fun’ climb up its own east arête, but this time I had more confidence in my route. Glissading and plunge-stepping down the snowy cirque, we made it back to camp near the footbridge on the JMT, 13½ hours later. Approximate route in red dots below:











---------- TRIP SUMMARY ---------------------------------------------------------------------------------------

Total Mileage: 28+ miles

Night #1: Lost Claim campground outside Yosemite NP on route 120 in Stanislaus National Forest. Elevation: 3500’.
Night #2: Along JMT in Lyell Canyon, just below footbridge, about 9.5 miles south from Dog Lake Parking lot in Tuolumne Meadows. Elevation: 9600’.
Night #3: Same as night #2

Conditions [pre-trip prediction]: Sunny days and windy; with partial snowcover on the trails, slushiness, muddiness, and fast flowing streams. Expect decent amount of snow off-trail and at higher elevations. The Lyell glacier I expect to be hard, crusty snow, and some scrambling requiring both hands, and stowing the ice axe on the pack. I hope post-holing is not a problem; as I am opting not to bring snowshoes.

Conditions [post-trip]: Conditions as expected for the most part. Warm and sunny typical Sierra weather, with highs in the mid 60’s and lows in the high 40’s at night. There was a bright full moon. Zero wind on the summit of both Lyell and McClure in the early afternoon, although it appeared that higher winds were sweeping over the summit in the mid morning (~10am) as we approached the glacier. Snowcups were present all along the route, about 18” in diameter, soft in the morning, softer later in the day. The entire route was slushy snow except for the very top of the chimney, where the glacier was covered by only 3” of crushed ice (snowcone-esque). Underneath was hard, impenetrable ice, that I believe was the very top of the Lyell glacier itself. Overall, conditions were excellent.
