Mount Diablo Ride

Warning: dial-up users beware, many pictures (31).


Engaged in a bit of road riding on Friday: Mount Diablo (3849 ft) via North Gate Road. It was a 55 minute, 48 mile (76.8 km) drive up north to the city of Walnut Creek for this excursion.



Here are the track points made by the GPS device I brought along with me. Again, the blue "line" is actually made out of many individual blue diamonds (in this case, 1777 of them), each representing an electronic "breadcrumb" left by the GPS unit.



The elevation profile of the ride. TOPO!'s interface is a pain to use. It is like Windows 3.1, only buggier and 10 times slower. (If you are too young to know what Windows 3.1 is, thank your lucky stars.)



Walnut Avenue, one of the roads which lead to North Gate Road. (No, the hill on the left is just that, a hill. Mount Diablo is some distance behind these foothills.)



North Gate Road. Cute. I wonder if the pets are that happy though.



Approaching Mt. Diablo: on either side of North Gate Road, houses and gated communities on flattened hills have replaced what used to be picturesque hills and lush meadows. Another cyclist / blogger who rode through this same stretch quoted Don Henley's lyrics on the raping of the land by yet another family in pursuit of the American Dream:

Some rich man came and raped the land,
Nobody caught 'em;
Put up a bunch of ugly boxes, and Jesus!
People bought them!


To which I deign to add my selection,

And they called it paradise,
The place to be.
They watched the hazy sun
Sinking in the sea.

. . .

And you can see them there,
On Sunday morning
They stand up and sing about
What it's like up there
They called it paradise.
I don't know why.
You call someplace paradise,
Kiss it goodbye!


Yeah, I'm in a sanctimonious mood today.




200 feet of easy climbing bring me to the North Gate Entrance of Mount Diablo State Park.



From here, one encounters a series of mild rollers (uphills and downhills) until the 3 mile mark, whereupon North Gate Road maintains an average grade of 6% until the junction at the elevation of 2000 ft.



My cyclo-computer / altimeter is off by 145 ft due to a low pressure weather system. Here am I celebrating what I thought was the 1005 ft elevation mark when I was actually at 860 ft. The error is consistent though. I just had to subtract 145 ft from the readings throughout the ride. (Yes, I could have zeroed it against one of the markers, but I was too lazy.)



The real 1000 ft elevation mark. In Scooby's lingo, I would say we have one Montebello (~2800 ft) to go before we make it to the summit.



View downhill at the 1000 ft elevation mark.



With a grade of 10%, the S-turn curves are there as an additional challenge on the ascent. Conversely, these same S-turns make for a lot of white-knuckled games of chicken versus the asphalt on the way down.



2000 ft elevation mark. Breathe. Breathe. Breathe. You are one big breathing machine, with legs that spin a pair of crankarms forever. The ranger station is 1/3 mile further on.



Junction Ranger Station. I can't get over the size of the building. It's so... quaint. I don't see a drinking fountain. From here, one has the choice of taking South Gate Road 6 miles (9.6 km) and 2000 ft downhill to the South Gate Entrance, or climbing another 4.5 miles (7.2 km) and 1800+ ft via Summit Road to the top.



Summit Road climbs up relentlessly at an average grade of 6.5 to 7% to the peak. The most difficult part of this climb? It is not the grade (though burning thighs and having to breathe harder is a bother), but the scenery. It is gorgeous, and if you brought a camera along, you might just find yourself indulging in more photography than cycling.



Attempted to take a picture of the summit from this turnout, but passing clouds block the view.



Much better. The red arrow denotes the Summit Observatory / Museum.



Diablo Valley Overlook. One is supposed to be able to see Mount Tamalpais from here, but it was too cloudy today.



3000 ft elevation mark. You are the Energizer Bunny: it keeps on going, and going, and going...



Devil's Elbow: elevation 3480 ft. Almost there.



Devil's Elbow. The signpost in the preceding picture is located at the lower right hand corner. After this point is a 10% grade section, where most cycling buddies, no matter how close, designate as a "no talking zone."



The last 1/8 mile (200 m) to the summit. With a grade of 17%, climbing it has been described as a "religious experience." I am a believer.



The summit of Mount Diablo and the Observatory / Museum.



The clouds I climbed through (and also blocked a previous picture) to get here.



Moi.



Mount Diablo Summit Observatory Viewing Deck elevation: 3895 ft (46 ft above the natural elevation of the peak). The gold/rust colored object is an early aviation beacon, which produces a light equivalent to 10 million candles, and was used to guide aircraft flying into the bay area before World War II. It was removed from service on Dec 7, 1941, as a wartime security measure. It has since been refurbished and now serves as a reason for morons to climb this 3849 ft mountain to "Ow" and "Ah" over it. Just kidding. The light is operated one night each year on Pearl Harbor Day (Dec 7). On that day there is also a sunset memorial service, with survivors of the attack present.



Attempted two panoramas this time as the wind was knocking me around.



Second try. Wind still knocking me around. There are drawbacks to being a lightweight, I guess.



For those into geology.



Descending Summit Road. Remember the clouds earlier? It's cold and wet riding through them at 25 - 35 mph (40 - 56 km/h).


A chilly 4.5 mile (7.2 km) descent later, I'm back at the Junction Ranger Station. There isn't enough time to go 10 miles (16 km) down South Gate Road to Danville, turn around and climb back up to this junction again (thus clocking another 2000 ft of climbing), and take the final descent via North Gate Road back to my car. Although mountain lions are rare in this area, I really didn't fancy being caught in the dark again (I did bring lights though).


Although I was still shivering and my teeth chattering (one word: windchill), the rest of the descent was a blast. There are very few blind corners, so you can take the corners as fast as you dare. Just watch out for the rangers with their radar guns on weekends. The speed limit ranges from 15 mph to 25 mph (24 km/h to 40 km/h). Some say that a speeding ticket on a public road while riding a bicycle counts as a moving violation. I'm not sure if that is true, but I sure don't want to find out. (Yes, the sunlight is really golden...)


Epilogue:
Total distance: Cyclo-computer 28.1 miles (44.96 km) /
GPS + TOPO! 27.44 miles (43.9 km)
Total elevation climbed: Altimeter 4300 ft (1311 m) /
GPS + TOPO! 4292 ft (1308 m)
Temperature range: 56 F (13.3 C) to 68 F (20 C)
Fluids consumed: 2.5 liters.

This ride was conducted solo.

Mount Tamalpais Ride Addendum



Finally received the GPS software and have been mucking around with it. Here are some of the results.


The red line is the entire route. The blue line, overlaying the red, is actually a large number of blue diamonds, each representing a discrete GPS trackpoint. For some reason, the GPS unit had more trouble maintaining a lock on the streets of San Francisco than on the mountains and valleys in Marin.



Elevation profile. The blue diamonds each represent a trackpoint left by the GPS device.



My housemate took the GPS data, fed to Goggle Earth, and obtained the follow interesting results.

This a view of part of Coastal Trail descending from Coyote Ridge (elevation 900 ft) to Muir Beach (sea level). You not only can set the angle of the view, but the altitude as well. The "eye" here is looking straight down from 1437 ft.



The "eye" is now at a theoretical altitude of 822 ft and looking east. On the right is the descent of Coastal trail to Muir Beach in the center, before climbing 450 feet up Shoreline Highway 1 to take Coastal trail (on the left) 2121 feet upwards to the East Peak of Mount Tamalpais. You can also see a little bit of Eldridge Grade as it winds down the flanks of the mountain.



Eldridge Grade's torturous turns as it descends from the East Peak of Mount Tamalpais, as well as the giant rollercoasters of Old Indian trail (section after Dawn Falls).



I find this especially humorous. Look at my tracks. Like a mouse in a maze. Yes, I was lost here.



After 14 hours 9 minutes, the GPS device finally ran out of batteries.



706 Meadowsweet Drive, where I stayed for the night.



Distance manually measured with map and mechanical mapwheel = 65.12 miles / 104.19 km.
Distance measured by GPS device and TOPO! = 65.70 miles / 105.12 km.
I guess I wasn't too far off :-)

Mount Tamalpais Ride

Warning: dial-up users beware, many pictures (60).


Decided not to wait any longer for my GPS software to arrive. I don't know when the owner of James Associates is going to return from his Labor Day holiday and get round to mailing my CDROM, so here is my trip report minus the elevation/distance charts.

Update: elevation profile added here.

Prologue:
After several non-starts and postponements, I had it and, despite not having slept a wink the night before (Bad idea. Don't do it), decided to attempt Mount Tamalpais, off-road and from San Francisco. And so, I left my apartment at 5:45 AM on Aug 31 2005 with my pack to catch the 6:01 AM northbound CalTrain to San Francisco.




Here is a map. The black line originating from the lower right, from the San Francisco 4th and King CalTrain station marks the to and fro route on the San Francisco side. The red line was the planned (longer) return route, where I will bag Stinson Beach on the way back. After the red dot, which marks the summit of Mt. Tamalpais, the black line marks my actual (shorter) return route.




San Francisco 4th and King CalTrain Station 7:45 AM Aug 31, 2005.




Half a mile north of the CalTrain station: it was only here that the Garmin Forerunner 201 could get a satellite lock.




Tourist trap Pier 39 Fishermen's Wharf at 8:30 AM.




Panorama view: the artificial lagoon on your right is Aquatic Park, home to several historic sailing ships and the training ground of many cold-water swimmers. Right behind the trees is a 262.4 ft (80m) climb to the top of Fort Mason (which is now an affordable hostel).




Panorama view from Fort Mason: Golden Gate Bridge, Slacker Hill, Sausalito and Tiburon in the distance.




Crissy Field recreational area. Lots of cute dogs here.




Crossing the Golden Gate Bridge on the east side.




A view of the Marin Headlands from the center of the Golden Gate Bridge. From left to right: Hawk Hill (900 ft), Kirby (900 ft), and Slacker Hill (930 ft). The road leading up is Conzelman Road.




Conzelman Road peaks at Hawk Hill before meandering down to Point Bonita Lighthouse.




Coastal trailhead. The shrubs and bushes along the trail are not as friendly as they seem: some of them are Poison Oak. The sign state: Rodeo Beach 2.7 miles; Tennessee Valley 7.0 miles; Muir Beach 12.2 miles. The yellow flowers on the right are those of the Dill weed (tastes really good in scrambled eggs).




A view of Rodeo Valley from the Coastal Trailhead. Mt Tamalpais can be observed in the distance.




Descending Coastal Trail was a blast (no rangers with radar guns and $135 speeding tickets for going over 15 mph on weekdays. Woohoo!). Taking a breather at the Marin Headlands Visitor Center parking lot. Rodeo Trail, lagoon, beach and Fort Cronkhite behind me. Rodeo Beach has the prettiest multi-colored sand particles, in different sizes. Someday I will drive up there with a glass bottle or two and fill them up as keepsakes.




This picture needs no introduction: Miwok trailhead (elevation 30 ft). The foliage may look romantic, but they mainly consist of Poison Oak. Personally, I prefer the previous picture.




Miwok trail (elevation 600 ft): a view of Tennessee Valley (elevation 200 ft), and Coastal trail, which climbs to 900 ft.




Old Springs trail: sweet singletrack that bombs down to the Miwok Livery Stables. The trail on the left is the return portion of Miwok trail from Muir Beach.




I became overconfident due to my new tires' phenomenal cornering grip and forgot that, while I can corner faster, I haven't learned to read my line that fast yet. My front wheel went into a deep rut after a corner. The result? A spectacular crash and "endo" at speed. A friendly bush caught me though. Whew! My left pedal released my foot, but not my right. One bolt ripped out and the cleat position was displaced.




As I did not think to bring spares (who would think to bring spare cleat sets???), I thought the ride was over. Then, upon examining the assembly, I realized that Shimano engineers are geniuses. There are four bolt holes in the mounting plate. The cleat only need two to function. I.e. the other two are redundant. Praying that it was the mounting plate's threads that stripped and not the bolt's, I rotated the mounting plate top to bottom, and Voila! I'm back in business.




Ripeness is all: the aroma of horseshit in Miwok Livery Stables greets me. Breathe, my friend! Breathe! *Choke!* *Gasp!* *Retch!* I know I've taken a picture of this before but I love this sign.




Halfway through Coyote Ridge trail downhill: taking a break to let my brakes/rims cool (you don't have to do this with disc brakes). A view of Muir Beach, Muir Beach Overlook (elevation 500 ft) and Muir Beach Community.




A panoramic view. East Peak of Mt. Tamalpais on the right.




Muir Beach. Had a lunch of an energy bar here. It's pretty ridiculous that Muir Beach lacks a water source / water access point for the public. The silver container with a black flip-top in the other bottle cage is a Cage Rocket, which contains my Gu Energy Gel, energy bars, Espresso Shot candy and rehydration salt mixes.




After 500 feet of climbing along Shoreline Highway 1: Muir Beach Overlook. The first time I visited this place on a bicycle.




2/3 of a mile north of Muir Beach Overlook is the Coast View Trailhead.




View of Shoreline Highway 1 snaking northwards towards Stinson Beach.




The trailhead is easy to miss from the road if you are driving. On the right is my destination: the East Peak of Mount Tamalpais.




Junction with Heather Cut-off Trail.




Shoreline Highway 1 and the Pacific Ocean below me as I climb up Coast View Trail.




Coast View Trail begins as an unshaded singletrack meandering up the mountain, slipping into shady groves like these...




Only to wind its way out...




Looking southward. After the junction with Deer Park Fire Road, Coast View Trail turns into Coastal Fire Road.




1000 ft of climbing later: Pantoll Ranger Station (elevation 1500 ft).




Second lunch break: another energy bar. Yeah, it comes out looking like this as well (and probably tastes the same too!). Highlight: as I was munching, I lost count of the number of thumbs up, "V" signs, and honks, made to me by passengers and drivers as they whizzed by on Panoramic Highway.




Onward to the summit: Old Stage Road.




Fresh air and a gentle incline with dappled sunshine = heaven on wheels.




Climbing upwards towards West Point Inn (the patch devoid of vegetation on the left). Also, a view eastwards of Mill Valley, Strawberry (the first peninsular) and Tiburon (the second peninsular).




Old Stage Road hugging the side of the mountain.




West Point Inn (elevation 1780 ft). A possible place to crash in if one can't get off the mountain before dark. Rustic accommodations at $30 a night with a tiny shared 5' x 5' bathroom out in the back. No electricity though. Not sure if they have hot water either. Better than being mountain lion bait out there in the night, I guess. Note: no sheets or blanket provided. Brrrr!




Just found out from a website that West Point Inn sells bottled water, lemonade, energy bars, and other goodies, all for a very reasonable $1 a piece. A couple glasses of cool lemonade would have been heaven. I should have gone inside (like the guy who took this picture).




Taking a break and contemplating Mount Diablo across the bay.




A view of the East Peak of Mt Tamalpais from Old Railroad Grade.




Onwards to the top...




East Peak Gardner Lookout of Mount Tamalpais (elevation 2571 ft / 784 m). The structure is used by the Fire Service to spot wildfires.




Moi. No, I'm not taking a whiz.




Summit panorama: from left to right, Lake Lagunitas, Richmond-San Rafael Bridge, Mt. Diablo.




What was hidden by the wall on the right: Strawberry, Tiburon, Angel Island, Richardson Bay Bridge, Sausalito, Marin Headlands, Golden Gate Bridge, San Francisco.




The descent.




7:25 PM: spent too much time resting on a bench, eating and hydrating, and now I have less than 20 minutes of daylight left to get off the mountain. Ordinarily, I would not have chosen this trail, as it is rated "difficult" and described as "rocky," but a passing rider said it was "not that bad." Well, I forgot that he was riding a full-suspension mountain bike.

Boy, did I find out just how difficult: the upper section of the trail is littered with loose rocks the size of apples, grapefruits and melons. Hardtails have a difficult time dealing with these, especially at speed. Had a nasty crash here. No friendly bush to save me this time. Landed on rocks. Huge bruise on right thigh (6 inches across), bashed my right knee, and bent the rear derailleur hanger (either that or I bent the XTR rear derailleur). I sure hope Specialized still stocks spare parts for my bike, or else it's time to hunt for another frame. Later, back at home, I found a write up on Eldridge Grade with the warning that "riding down Eldridge Grade will remove any loose fillings." Well, it certainly earned a testimonial from me.




Before Eldridge Grade swings north, it branches southwards into a monstrous roller-coaster trail called Indian Fire Road. That was the next trail I had to take. With peaks as high as 60 feet and dips just as deep, these huge jumps must be exhilarating during the day, absolutely terrifying in the dark. Got out of the forest at 8:14 PM onto Crown Road, Kent Woodlands.




It was rather difficult trying to find the bike path corridor at night, all the more so when I have never seen it during the day. I cycled around the cities of Kentfield, Greenbrae, Lakespur and Corte Madera for 2 hours looking for the bike path, occasionally locating sections of it, riding them for 10 to 15 minutes, before being inevitably lost again. It was incredibly frustrating. I was also getting tired, hungry, and cold.

The final hurdle involved locating a section of the bike path which leads to a tunnel under Alto Hill. I cycled around the city for an hour, never realizing that it was 50 feet away, right across the street. My tired mind assumed that the structure was just another sheltered bench for park users. When I finally realized my error at 11 PM, I was too tired to continue. I also realized the futility of rushing back to San Francisco to catch the last southbound CalTrain (12:01 AM) as the Golden Gate Bridge is closed to pedestrian and cyclists after 9 PM. Postscript: I later found out that the map I bought is erroneous (one of its many). The Corte Madera - Alto Tunnel is not open to passage yet. Note: found out that cyclists can cross the Golden Gate Bridge at all hours on the East side. Stand before the gate (where the security camera can see you) and press the red button. A buzzer will sound and the gate will slide open. Repeat on the other end of the bridge.




12:30 AM Sept 1: heated motel room, hot shower, and a $12 artery-clogging sourdough burger on the table. I think I earned it. All I had to eat were the entire day were 5 Gu Energy Gel packets (100 calories each) and 3 energy bars (220 calories each). In any case, I only slept 90 minutes due to exhaustion, after which I was awaken by the pain from my crash wounds (aspirin didn't help). Still, IMHO, the hot shower alone was worth the price of admission.

While I was futilely trying to get some more sleep, my housemate was driving around Mill Valley the entire night, cruising the streets looking for me. So sorry, dude. Next time I will be sure to call him a second time--to let him know that I am safely holed up somewhere for the night. My bad : (




7:30 AM: View from outside the motel, on Meadowsweet Drive. Mount Tamalpais is hidden behind the fog. A little chilly (52 F / 11 C) and windy this morning.




After a series of short climbs up to 200 ft, Meadowsweet Drive loops back north to become Casa Buena Drive. Looking north, the city of San Rafael and San Pedro Mountain in the distance.




City of Alto: entrance ramp to bike corridor towards Sausalito. It's all road riding today: no need for my visor. Trying not to look too sleep-deprived here.




The bike corridor that is supposed to emerge from the other end of the Corte Madera - Alto Tunnel. What I have done then, is to circumvent it, as illustrated in this picture.




Wheelchair access ramp to the bike corridor. I wonder what sort of grade (%) they are limited to, or else there is no practical reason why they will build the ramp with this number of switchbacks.




Panorama: left to right, Strawberry, Richardson Bay Bridge, Mill Valley - Sausalito Bike Path (southbound), Marin City, Tamalpais Valley.




For some reason, the marsh reminded me of the Dead Marshes in Peter Jackson's film adaptation of The Lord of the Rings. Maybe it is the rich deep hue of green. Or maybe it is because I only slept a total of 1.5 hours in the last 48 hours.




Downtown Sausalito. A hundred yards down, on the left side of the street, is a hole-in-the-wall place that serves really good burgers. At $14 for a cheeseburger, regular fries and a regular soda (no free refills too!), they sure don't charge hole-in-the-wall prices though.




Crossing the Golden Gate Bridge again. The morning fog hasn't completely burned off yet. Time now is around 10:45 AM.

Reached the San Francisco 4th and King CalTrain Station at 11:22 AM.
Returned to apartment at 1:17 PM Sept 1, 2005.


Epilogue:
Total distance: 65.12 miles / 104.19 km.
Total elevation climbed: 7708 ft / 2350 m.
Temperature range: 52 F (11 C) to 79 F (26 C)
Amount of fluids consumed: 14 liters.

Self-portraits were taken using UltraPod II.

This ride was conducted solo.

Stinson Beach for another day's ride then.
