The eastern span of the San Francisco-Oakland Bay Bridge, an update: 23 November 2015

I was interested to see how much progress has been made removing the old portion of the bridge. When the new bridge section was first opened Caltrans stated that the bicycle/pedestrian pathway should be completed to Yerba Buena Island by the end of 2015. The completion date has now been pushed back to the summer of 2016. It is a work in progress. Here are pictures I took while walking on the pedestrian/bicycle pathway.

A visit to Lake Chabot Park to explore Nike Missile Site SF-31L/C: 21 November 2015

Nike Missile site SF-31 had two components that by design were physically located in two separate locations. The locations are about 1.5 miles from one another.

1. One component is the Nike Missile launching site (SF-31L), where the missiles were stored underground and were able to be fired towards incoming airplanes, in the event of an enemy attack by air. An East Bay Regional Park service yard now occupies the former Nike missile launching site. The service yard is closed to the public, but friendly service yard personnel allowed me the opportunity to walk through the site and photograph the remnants of the Nike missile battery. Two of the underground Nike Missile storage/launching sites are currently visible in the service yard. 

2. The second location of the Nike Missile site is the radar communications and control facility (SF-31C). I left the East Bay Regional service yard and drove about two miles west on Fairmont Drive. I then parked in the small parking lot at the beginning of the Fairmont Ridge Trail. It is the trail that leads to the former Nike Missile radar location (SF-31C) where missile targeting and fire control took place. The former Nike Missile radar site is now occupied by the radio transmission tower of KYA-FM San Francisco, and microwave repeater communication antennas.

The remains of a hydraulic lift used both to store missiles underground and also raise missiles to ground level for firing. After the missiles had been raised, the missiles were rolled by hand a short distance from the hydraulic lift, raised up and put into firing position. These were surface to air missiles with a range of between 25 and 50 miles. They were designed to protect the continental US from an enemy attack from the air. The Cold War was active at the time, and the main concern was that the Russians would launch a surprise attack. Click on the image to see the full-size photograph.
The missile storage areas are still underground. Each storage area was capable of storing 8 Nike missiles. I was able to locate two underground storage areas. The storage areas are located about 30 feet underground. An underground storage area interior dimensions are about 40 feet wide by 75 feet long and 15 feet high. Click on the image to see the full-size photo.
I believe this was designed to be an emergency exit from the underground missile storage area. Click on the image to see the full-size photograph.

At the end of the Fairmont Ridge Trail is the entry to the former SF-31C Nike Missile Radar Station. The site is currently being used as an FM radio transmitter location, and it is fenced and inaccessible to the public. Click on the image to see the full-size photo.

Nike Missile Site SF-93A/L/C - San Rafael, California: 11 October 2015

 I spoke with an Army veteran who described his experiences when he was stationed at Nike Missile Site SF-93L in San Rafael, California. I had little knowledge of the San Rafael Nike site, and listening to the veteran describe his time at the site convinced me to locate and view both the launching site and the radar site. After reviewing some maps of the area and recording the necessary latitude and longitude coordinates on my GPS, I was ready to do some exploring!

Click on an image to view the full-size photograph.

A view of SF-93A, the Nike Missile Site Administration Area. It is now occupied by a drug and alcohol detox center. 

This photo was taken sometime between 1956 and 1971, when the missile site was active. A view of the Administration Area (SF-93A) is seen in the foreground, and the Launching Area is on the top of the hill  (SF-93L). The Launching Area is at an elevation of 97 feet, and the Administration Area is at the height of 10 feet. This view is looking southeast. San Francisco Bay is at the upper left of the photo (GGNRA).

A Google Earth view of the launching site. The red line shows the route I took as I explored the area. The blue circle indicates where the missile launchers were located. US Route 101 (aka Redwood Highway) can be seen on the left. 

Here is a view of the SF-93L Launching Site. The picture is looking northeast. The three launching areas and underground missile storage areas could launch four missiles simultaneously. They have all been covered with up to seven feet of dirt. A little concrete and asphalt are the only indication of what was once there; it is not easy to locate. 

The launching site, looking west. Mount Tamalpais is in the distance. 

I left the SF-93L launching site and drove a few miles south to a trailhead on San Pedro Mountain. My plan was to ascend single-track hiking trails and dirt fire roads to 984 feet, the elevation of SF-93C, the radar site. This picture was taken during my hike up Gold Hill Trail on San Pedro Mountain. Downtown San Rafael is conspicuous, with beautiful Mount Tamalpais gracefully overlooking the scene. The view is looking southwest. 

This view is looking south. San Rafael Creek is visible, as is the industrial/warehouse area of San Rafael. 

Here is a Google Earth view of the route I took to and from the radar site. The approximate distance traveled was 5.3 miles. The approximate cumulative elevation gain was 1,249 feet. The blue circle depicts the location of the radar site. 

A graph of the elevation changes encountered in the route. 

SF-93C radar site. 

I noticed this survey marker at the radar site. The marker was installed by the US Army Corps of Engineers in 1975. 

SF-93C radar site. 

Hamilton Airfield was initiated in 1932 as an Army airfield. It then became an Air Force airfield and finally reverted to an Army airfield. In January 1976, it was placed in US Government caretaker status. The airfield was located just above sea level, as seen in this photo. This photo was taken from the SF-93C radar site. The view is looking north. 

The Marin County Civic Center was designed by Frank Lloyd Wright. Construction began in 1960, and the building was completed in 1962. This view is from the Scettrini Fire Road on San Pedro Mountain. The view is looking northwest.

A six-unit apartment building located on Noe Street at 14th Street. 
1450 Masonic Avenue. 
The route was tracked by GPS. The distance traveled was approximately 4.5 miles, and the approximate cumulative elevation gain was 413 feet.
