DEBUNKING: San Francisco Chronicle’s Repeated Claims of How “Mountain Biking Started on Mount Tamalpais”

Tuesday, September 8th, 2015

Here you go:

“How mountain biking’s mega-success started on Mount Tamalpais”

Right here:

“When Joe Breeze did what thousands of Mill Valley kids had done before him — stood on Miller Avenue across the street from the 2 a.m. Club and stuck out his thumb to hitch a ride — he didn’t know he was changing history.

Let’s chalk some of this up to a kind of CW Nevius-style local rah-rahing.

Now let’s compare that with a less patriotic, a less Bay Area-centric source like Wiki.*

What’s that, it was only the “mega-success” of MTB what got started on Mt. Tam?

Al right, but that means Cascade Canyon Road is on “a western ridge of Mt Tam …”

“They all came together to race Repack, a steep downhill drop on a western ridge of Mount Tam, plummeting 1,300 feet in 2.1 miles.”

…as opposed to it being on nearby Pine Mountain, right?

Here’s the map:

So on this map (which isn’t exactly pointing north, oh well) the peaks of Mt Tam are on the lower right, and Pine Mountain is on the left across a chain of lakes, and Cascade Canyon Fire Road (aka “Repack” – you can’t expect Marin Co guv’mint/The Feds to honor that bike-centric name) is in the upper left.

Here’s another map, with Mt Tam way off your screen, down and to the right – knock yourself out.

Anyway at least now, a Chron writer is showing his/her work. So, if you think Pine Mountain / the San Geronimo Ridge / Cascade Canyon Road/Repack is a part of Mt. Tam, then, maybe mountain biking gestated, a little, on Mount Tam, sort of.

But if not, then not.

I’ll tell you, IRL, Repack is way far away from the West, Middle, and East peaks of Mt Tam, so that’s why I’m saying mountain biking was NOT born on Mt Tam.


Know Your Ornery Anna’s Hummingbirds of the Presidio – El Polin Springs are Certainly Worth Fighting Over, No?

Hummingbirds are the orneriest of critters – they simply cannot abide, you dig?

Anyway, see if you can follow the action here at Tennessee Hollow in our Presidio:

An Unexpected River in the Presidio on the Arguello Bike Line

Tuesday, October 28th, 2008

This is what it looked like the other night on dark, dark Arguello Avenue coming up out of the Main Post near Infantry Terrace. An unexpected river flowing down the bike lane, leaving you with the option of just pushing your rig uphill on the sidewalk (which some people do anyway, owing to the steepness).

A busted water main or another unearthed spring?

You make the call.

Why Don’t YOU Help Restore Tennessee Hollow at the Presidio?

Saturday, September 13th, 2008

What’s Tennessee Hollow? Check it out here on this map: Tennessee Hollow Watershed Self-Guided Walking Tour. It’s the home of El Polin Springs, the site of recent tours hosted by the Presidio Trust.

Take a look at the Overall Tennessee Hollow Restoration Project Timeline and then decide if you’d like to finance the restoration of this area from about 2010 to 2015. You might be able to do it. All it would take is something like low 8-figures. Seriously. Are you going to live forever? How will people remember you?

Now, on with the show.

Damien Raffa, Presidio Trust Education/Volunteer Program Manager, guides some of the 100+ people who showed up for today’s walking tours. (The future doesn’t look bright for the housing and car parking spaces seen in the background.) Click to expand:

This is it, the spring itself flowing over a notched dam (aka weir) to the delight of a thirsty Allen’s Hummingbird.  

FYI, hummingbirds don’t like to share so they are in constant battle over access to the spring. This reliable watering hole attracts all sorts of birds and bird watchers.

Stone well at El Polin Springs. The metal plaque that should be in the foreground was stolen in 2005, possibly by filthy dog-owning “white thrash” per Francisco Da Costa.  

Here’s how you can ENJOY THE WATERSHED. See you there!
