FINALE – Hutchinson Co. Quarry, Larkspur Landing, CA
***

Heading east on E Sir Francis Drake, Hutchinson Co. quarry in the distance
***
Having passed under the railway trestle the bus lurches east on Sir Francis Drake toward the Hutchinson Co. Quarry.
***
The Hutchinson Co. mill lay ahead at the point where Sir Francis Drake Boulevard curves south east. The bus failed to take the curve, went through the fence, and into the quarry.
***

Hutchinson Quarry was straight ahead where the road curved south east
***
A visitor to this area in 2009 will find that the Hutchinson Quarry site has been obliterated by Larkspur Landing mall and apartments. There is nothing left from 1971 that is identifiable, no relics, no commemorative plaques, nothing.
The same view down the road now looks like this (below) – look closely, you can see the cliff edge that once surrounded the lake:

A Courtyard Marriott hotel sits over the top of where quarry buildings once were. You can grab a coffee from Starbucks, which sits close to where the lake was, and then walk onto Old Quarry Road.

2009, the name says it all

But where was the lake located?
A photo at The Geologic Foundations of Ring Mountain page is useful for two reasons. Firstly, the author, discussing the scene from a geological perspective, says “…The light colored rocks in this photo are rhyolites used to fill the pond where Dirty Harry finished off the bad guy.” (Source) Secondly, in the top right corner of the same image were newly built Larkspur Shores Apartments. The photo is undated but shows condos located at the corner of Old Quarry Rd N and Lincoln Village Circle.

There’s also an excellent aerial view (thumbnail preview below) from historicaerials.com which will let you see the location as it appeared in 1946. 1946 is the only image at the site that let’s you see the area before it was developed. Look closely and you can see the shadow of the mill building and the twin conveyer buildings right behind. It appears that the lake bed was dry at that time. If you visit the link be sure to toggle the ‘Overlays’ button, and select ‘All Roads’ to see how the roads today sit over the old quarry location.

As credits start to roll the view looks west up Sir Francis Drake toward the trestle. You can see Wood Island, which years later became the car park for the Golden Gate Ferry service. To the lower right of the frame 01:37:46 (below) is where Old Quarry Rd is situated today.

Old Quarry Rd N, as it is now known, continued around the back of the old lake and is now a carpark. The location of where the carpark now lies can be seen behind Scorpio at 01:34:46 (below):

An excellent home video clip of the lake being filled in 1988 can be watched here at youtube.

In 2009, Old Quarry Road N is a quiet lane of carparks for the apartments built over the lake. Next to the carpark, over a slight ridge, is a track where you can walk along the base of the cliffs that can be seen in frame 01:34:46 (above):

The ghost of the lake lives on. The object in the photo below, located where the track ends close to Lincoln Village Circle, appears to be a wick drain. Wick drains are designed to accelerate the time it takes for compressed earth to settle by allowing water to escape. Peering down into it I could see water about 20 feet below.

Man I wish that lake was still there. How many of us would love to go there now and toss our metaphorical badges into that lake?
I’ve enjoyed your web site very much. This film has been one of my favorites, ever since I first saw it in the early 1970′s. Great job.
Hey very nice blog!!….I’m an instant fan, I have bookmarked you and I’ll be checking back on a regular….See ya
There is a pretty cool website called HistoricAerials.com that allows you to access old aerial views of populated areas. This particular area has a view from 1987 and then jumps back to 1946. It shows the mill and the exact spot of the pond in question. Cheers!
Thanks for such a great website! I live in L.A. and have often wanted to go to San Fran to see some of these filming locations. You did a great job.
Thanks for the info, I had lived in Santa Rosa in 2009, I knew Larkspur was where the scene was filmed because of the RR trestle, but never knew that the quarry had been filled.
Take a metal detector to this area. See if you can locate Harry’s ‘Star’ he tossed into the old lake. Can you imagine how priceless a find that would be? Oh, man! That would be sheer gold!
Actually, I’d have asked a friend to shoot me with a paintball gun, blowing me into the lake, if it was still there LOL
Of course, they would’ve had to quote Harry’s line before shooting me. I wouldn’t let them do it otherwise!
Cool!
Like Doug said, look for the star. I’ve always wondered if that lake was still there and if anyone ever tried to scuba dive for it or something to find the badge. Man that would be one valuable piece of memorabilia. I could only imagine hundreds of people have already looked for it although I’ve never found anything online of people even looking.
Somewhere I read that director Don Siegel put a tarp over part of the pond being as how they didn’t have a 2nd prop badge to throw. Sorry to squash that treasure-hunting dream. .
When I was growing up in Marin, the quarry building was so dilapidated that when we drove by Mom always told us blow real hard and it will fall down. Despite our best efforts, it kept falling apart for years, but never fell down.
Around 1970 my father was an iron worker in the San Francisco Bay area, local 377, and his crew was assigned to tear down the Hutchison facility, but had to wait to two weeks because a film crew was using the site to shoot some scenes for a movie. I asked him if he know what movie was being shot, he didn’t know, but he did find out that it was some type of detective movie. My dad was also an artist, and found some rusty metal at the site he thought would be great for art projects. He did a couple of pieces of art, but then the metal sat for 30 years in his back yard. In 2000 he died, in 2003 my mother gave me the metal, and in 2010 I started a piece of art with it. One night I was flipping though the channels on the TV and caught the ending of Dirty Harry, and realized the metal was from the same place. The art piece is a contemporary American Flag cut out of this metal, and I called it Harry’s Flag.
I have always liked the Dirty Harry films, and I became a little bit obsessed late last year when after watching the film again, I tried desperately on Google Earth to find the lake. I first thought the quarry was somewhere to the south of SF, because of the freeway in the distance of the closing credits. It took close scrutiny of the latter part of the film, and the journey the bus took, to realise where the quarry was actually located. I was very disappointed to see that the lake was gone and had been built upon, and not being able to see how it looked now. I would still love to know the exact location; is it where the Mariott Hotel is, or some of the apartments; or is it where the retail park is? Hope to one day find out if someone can plot it on an image of the apartments/retail park. The film has made me want to visit SF on vacation from the UK, mainly to seek out the filming locations, but it may be a long time before I am able to do this. However, finding your site only a few days ago has been magnificent in me being able to at least see them in photos. Fascinating stuff and well done for a great site.
