Here it is:

Here’s how things used to be – dark, wet and smelly:

Area Yelpers are not yet yelping about the improvements, but they will, someday, I’m sure:

Marin Headlands: Tunnel and Scenic Overlook Parking/Pull-Outs

Tunnel re-opened June 3, 2017

Updated June 6, 2017

The major phases of the Baker-Barry Tunnel preservation project are complete. Crews have addressed fissures and cracks in the tunnel wall, pumped polyurethane into the gaps around the tunnel lining, and installed a new, more energy-efficient lighting system. The historic tunnel is now preserved to bring the next generation of park visitors to the Marin Headlands.

Parking and pull-outs are now open to vehicles on Conzelman Road east of the McCullogh traffic circle.

For a summary of the work to date and photos inside the project, read this recent article in the Marin IJ.

 

About the Tunnel Preservation Project: Safer Surfaces. Better Lighting.

This project repaired the tunnel’s concrete structure. Repaired cracks and leaks resulted in a slippery film of sediment that created a safety hazard for vehicles and bicyclists.

A new tunnel LED light system will reduce energy use by an estimated 40% from what was the single largest energy user at Golden Gate National Recreation Area! The new lights also better illuminate the tunnel for vehicles and bicyclists.

We also replaced water and sewer lines mounted in the tunnel. The outdated water and sewer lines were subject to frequent breaks which resulted in tunnel closures.

Frisco Boats vs. Frisco Whales – How Close is Too Close? – “iSailboat” Bears Down on Diving Humpback

Thursday, July 6th, 2017

IDK the answer to this question.

This is prolly the closest I saw the past week or so. A large Beneteau 40 sailboat (named iSailboat, worth what, a couple hundred thou?) east of the Golden Gate Bridge was just seconds away from having its hull or keel hitting this humpback:

You know, IMO.

Not real sailing here, just puttering around with the whales for a while.

Anyway, just saying.

Our SFPL Hosts an Event on August 6th for the Great Eclipse of August 21, 2017 – FREE PAIR OF VIEWING GLASSES

Thursday, July 6th, 2017

 

The San Francisco Public Library has got you covered with this whole partial eclipse thing:

“The Sky Event of the Decade: August’s Eclipse of the Sun – Receive free safe viewing glasses and tips for observing this once-in-a-lifetime event

SAN FRANCISCO, CA — San Francisco Public Library is pleased to bring Astronomer Andrew Fraknoi to the Main Library for a talk titled “August’s ‘All-American’ Eclipse of the Sun and How to View it Safely.”

On Aug. 21, there will be an eclipse of the sun visible throughout North America.  People in a narrow path from Oregon to South Carolina will see a spectacular total eclipse, with the moon briefly covering the sun, and day turning into night.  Everyone else, including those in the Bay Area, will see a partial eclipse, where the moon covers a good part of the sun.

On Sunday, Aug. 6, Astronomer Andrew Fraknoi will give a non-technical, family-oriented talk on getting ready for the “All-American” eclipse of the sun. Fraknoi will describe how eclipses work, why they are one of nature’s most spectacular sights, exactly when and where the eclipse of 2017 will be visible, and how to observe the eclipse and the sun safely.

Everyone attending the event will receive a free pair of safe viewing glasses for observing the sun.Copies of Professor Fraknoi’s new children’s book on eclipses, When the Sun Goes Dark, will be available for sale and signing after the talk. Like the book, the discussion will be appropriate for children 10 years of age or older, and adults.

Andrew Fraknoi is the chair of the astronomy department at Foothill College. He serves on the 2017 Eclipse Task Force of the American Astronomical Society, training teachers and librarians to act as guides for the public as the August eclipse approaches. He has appeared regularly on local and national radio, explaining astronomical developments in everyday language and was named California Professor of the Year in 2007.  The International Astronomical Union has named Asteroid 4859 Asteroid Fraknoi to honor his contributions to the public understanding of science.

The Sky Event of the Decade:  August’s “All-American” Eclipse of the Sun  Aug. 61-3 p.m., Main Library, 100 Larkin Street, Koret Auditorium”
