Rolling hills of concrete

A few days off in the SF bay area? Seems like an opportunity to go exploring.
First stop: hills. One of the things I’ve missed most about California.

Spotting/observation locations
Each of the spotting/observation locations (pillboxes) would have utilized an azimuth and depression finder to collect location information about attacking vessels. While none of them are present at the sites, the mounting point for the azimuth can still be seen at some.

Depression finder on the left, azimuth instrument (mounted on a tripod in this instance) on the right.

The remains of an azimuth base inside of a combination spotting and command post. A circular platform on which a depression finder would have sat was adjacent to this position.

Information was relayed to plotting rooms which would would be used to generate targeting orders for the gun batteries. None of these locations were along my route on this particular day.

	Decided I needed another day of the hills. While some of the anti-gas equipment was present, some of it appeared to have been removed recently. Originally installed in 1941 and marked (officially) as abandoned in 1948, the equipment was likely retrofit at some point following, as the location is marked as a radiological shelter. Edit, 03/30/2020 - it seems the anti-gas equipment was moved to Battery Townsley as part of its ongoing restoration. [last edit 3/31/2020 5:42 AM by inloc - edited 1 times]

	Spent another day working my way around the hills. Seems I've finally started to run out of the “hills”. What remains of a certain wooded bunker’s entrance. Sadly not so wooded anymore.
