SONORA PASS, NORTHERN CALIFORNIA OCTOBER 23, 2005

We'd push the limits this time, skipping the usual last Sunday in June in favor of a late-season Fall just-before-the-snow-hits ride. Just two of us this time, myself and Jeff K (whom I've ridden a number of centuries with, and is an earlier victim of Sonora Pass as well). Gorgeous day, temps starting in the low-50s and drifting casually up towards 80 at the far side. This is, as I've said before, a "greatest hits" ride. It's not very long at just 52 miles, but it hits up both sides of Sonora Pass, starting in Dardanelle, heading out to the Marine Camp near 395 and back.

This is also a ride whose spec's don't tell the story. It's only 7,000ft of climbing, which really shouldn't kill you. And the legendary grades? Yes, they're legendary in difficulty, but if there's to be truth in advertising, those signs warning you of 24-26% grades? That describes the worst-possible line through the worst corner. The reality is that the hardest sections average "only" 15%, most of them "just" 10%. So what makes it so difficult? Probably the fact that it starts out so darned hard! Just 5 miles out of Dardanelle and you hit the infamous section "window" section, over half a mile averaging 15%.

Directions to the start- From the SF Bay Area, head out 580 and follow the signs to Sonora (which is on Highway 108). Pretty easy; Dardanelle is about 52 miles up the road from Sonora. No way to get lost; the road only goes one place.

We've done this ride every year since 1998, but it's never been routine.

   
As with most trips these days, this one started out with an over-priced tank of gas, over $50 worth. Originally we'd planned to stay at Dardanelle Resort, but they weren't answering their phones (and when we got there we discovered why- they were completely locked up for the season!). So instead we stayed at the Alladin Motor Inn in Sonora. Nicer than most places in Sonora, and just over an hour from Dardanelle.   As always, the ride starts out quite peacefully, with no hint of what's to come. Nicely-paved road, not too much traffic (although truthfully, a bit more than we expected for this late in the season).

Don't let anyone tell you we don't have seasons, for "fall colors", in California!

After a while I have to admit that it does get tiring hearing people talk about how California doesn't have seasons, how we don't have the oranges & reds you see elsewhere. We do; you just have to get out to find them, and when you do that on a bike, it's especially beautiful.
   
The Stanislaus River is a nice companion on the lower (almost flat) part of the ride. It will later make an appearance now & then around Chipmunk Flat and wrap around the Golden Stairs (not true it turns out; that's Deadman's Creek), but at that point your eyes are having a difficult time making things out through the constant bath of seat coming off your forehead. Enjoy it now, while you can.
         
   
The infamous sign. 26% grade up ahead. It says 1 mile, but to be truthful, I've never measured it.   And here she is- the infamous "Window" where the grade theoretically hits 26%. The reality is probably closer to 20%; maybe if you got the inside of a corner you'd get 26? But it's steep, and really rude, especially so early in the ride. On the topo map, this is just above the 6713' benchmark. 615ft of climbing, 15% average grade, heart rate 108 at the bottom and 170 at the top.
   
After a bit we caught up to Eric, a guy from Santa Cruz who'd been in the area for a few days. For the next mile, the grade averages 10.4%.   The grade mercifully eases off to maybe 7% even a bit less for short distances, allowing you to see speeds as high as 10mph! This too shall pass, as you hit the next really steep section (shown in the next photo).
   
Why does it hurt so much? Probably because, before this "flat" 5% grade, there's a nasty 12%+ grade.   One of the several false-flats, although truth is, this one really is! Just doesn't feel like it's really flat.   Not shown is the noisy creek on the right, probably the headwaters of the Stanislaus, and a pleasant companion.
   
Ahh... Chipmunk "Flat." Which is anything but flat. But it's where you first notice the wall of granite you're heading directly into, with no way out. This is the entrance to the infamous "Golden Stairs." Hard to believe non-motorized vehicles can make it up the Golden Stairs, whether they were wagons from days gone by, or bicycles. What was the weather like? Check here for the weather station at 9250ft.   This if Jeff on the Golden Stairs, probably wishing he was on a motorized vehicle about now. It looks steep, but it's even steeper than it looks. 20% in fact. Check out the topo & aerial views!
   
Just past 9000 feet the Golden Stairs levels out to a pleasant 8% for a mile or so, and then what would normally be an easy 5% on the final run to the top. But after what's come before, it does not feel easy, and the top is a very welcome sight!   The run down the backside is... fast. Very fast. Beautiful views of the White Mountains in the distance.
   
Descending this, you're wondering just how bad it's going to feel on the return. You needn't wonder. It's going to be as tough as it looks.   Around 7200ft, the road levels out for a bit and you come across the Leavitt Meadows Pack Station on the right-hand side of the road. Just past, on the left (in the photo above-right), is a place the marines use for wall-scaling exercises, which normally has a large water tank where you can fill up on your return up the east side. This was the first time it was not there, giving us some concern about having enough water... not a good thing!
   
Here's the goofy thing. At the Leavitt Meadow Pack Station, someone had set out a pair of bottle waters on the front porch. Nobody was home; we were going to offer to pay for them, but didn't want to deprive someone else more desperate. Fortunately, there was still water flowing at a campsite faucet just down the road; this is not normally the case. Do not depend upon water being available... we got lucky.   It really is this pretty in the Sierras. Don't forget to bring sunscreen, as this ride is entirely out in the open. We did forget, and planned to buy some at the Dardanelle store... which was closed.
   
Approaching the Marine Camp (actually their winter warfare training facility), which for all intents & purposes was deserted. Even the guardhouse where a few years ago we found a couple of kids with M16s.   Lunch time! Basically a couple of powerbars and a nice concrete block to sit on.
   
Time to turn around & head back, after briefly contemplating riding another 3-4 miles out to Highway 395. The Marine camp is almost surrealistic, like some secret place you'd hear about in the X-Files.   That little climb back to Leavitt Meadows can't be all that much, but it's your first indication that it's a tough ride back.
   
Pretty strange when, in the middle of nowhere, someone drives by that you know. In this case, Bob & Tracy of Cycle Caifornia magazine. 29.88 miles into the ride, 7201ft.   Leaving Leavitt Meadows, you're back to the real grind. The sign tells you of steep grades ahead and warns big trucks and trailers to stay away, but says nothing about bikes. It doesn't have to, because you round that corner and kaboom, the first really ugly grade. It flattens out in a bit, and then... (Click here for a satellite photo, which can also be changed to a topo map, to get a feel for what the road does here)
   
...and then the first really ugly grade. You have the briefest opportunity to breathe between each one. Very brief. This is arguably the worst, and the most-beautiful. A very steep pitch with a switchback and great views. The next 1.24 miles average over 11%, but feels a lot steeper.   Sonora Pass toys with you once again, leveling out to maybe 5% with little bumps considerably worse.
   
Leading into and emerging from another step up the mountain. The front (West) side of Sonora Pass is much less varied in terrain than the back side, but while you'd think that would give you a chance to recover, it just doesn't work that way. Quite the opposite in fact, as your mind says it should be easier than it feels. (Click here for topo map)   Up to the final plateau before the top.
   
Yes, you're actually seeing a bit of downhill, and were it not for clearly seeing what's ahead for the first time, there'd be a sense of peace. However, where the road disappears in the photo at the right... that's where things get really silly. You head to the left a bit, the road pitches up nastily, a hairpin right, another quarter mile of nasty stuff and then you're at the top of something, looking at a short descent before the final climb (show in the far-right photo).   Who makes roads like this anyway, and how? How do they keep the asphalt from sliding back down the hill? This is the beginning of the final assualt on the top. The tough part is figuring out if you have time to go to your larger chainring and then back down. (Aerial view here)
   
Jeff powering up the final grade to the top. It's listed as 15%, and I believe it. At sea level it might not be so tough, and the curious thing is that you don't really feel like the altitude is getting to you, but something is. Probably the cumulative effect of having done both sides on the same day. Still, it's less than 8,000ft of total climbing, but it definitely passes the "tough ride" test of over 1,000ft of climbing per 10 miles! (Topo view & Aerial view).
   
Pausing to read a bit about the history of Sonora Pass. No mention of bikes.   Descending Blue Canyon is an amazing experience. If it's possible, it looks even steeper going down than it did coming up. This photo is just about 9000ft.
   
Another look at Blue Canyon, which is difficult to shoot with the afternoon sun.   Jeff stopping just below "The Window", admiring the view and giving the brakes a chance to cool, and then later heading down, fast.
    What does it take to do this ride?

The obvious- low gears. If you live on or near the San Francisco Peninsula, I'd suggest trying out Bohlman/On Orbit out of Los Gatos. Whatever you need to make it up that grade is what you'll need for Sonora Pass. Many of us are using "compact" cranks, 50/34 front with 12/27 rear. A triple would be even better.

Water. It can get hot up there, plus you lose a lot more water because you're breathing faster in the thinner air. Two full bottles on each side, which means refilling on the opposite side.

Food. No choice but to bring your own!
Look hard and you can see the scar of the road way way down, on the left. This is your final descent into Dardanelle.   One last stop just before the end, admiring the Stanislaus and the fall colors. 52 miles, 5 hours, just another day on a bike.
