The Blasting of Blossom Rock: Submarine Explosion

On April 23, 1870 engineers set off "the largest submarine explosion on record." The great submarine explosion was a stunning engineering feat, but also symbolic of a city that had grown in just a few decades from a remote backwater to become “The Paris of the West.”

    Some viewers have asked about the term "dead-head," which, of course has different meaning today. In 1870 a "dead head" was a person who got into the theater for free. For example, a person could volunteer to put up posters for the theater, and be allowed admission to the gallery. Despite not having paid for their ticket, they were often critical of the performance.

    I watched the explosion of Ripple Rock on TV in 1958. Ripple Rock was a navigation hazard in a channel between two islands north of Nanaimo, BC. The tides through that channel were very difficult and more than one ship was wrecked on it. Miners working from a nearby island dug down, dug under the strait, and dug up under the reef and filled it with explosives. For me at 5 yrs old it was just a big gush of water of water. It was at the time the largest non-nuclear explosion in history. It's still the third largest and still the largest under water non-nuclear explosion.

    Definitely seems like a small lighthouse would have been a better choice - either masonry or what was then the new "caisson" lighthouses. They've been built on worse rocks than this one. In fact, Barton Alexander knew a thing or two about building lighthouses in such conditions having supervised the construction of Minot's Ledge Lighthouse. That makes me wonder if Alexander (and Williamson, who was the Lighthouse District Engineer) explored the possibility of a lighthouse and advised against it, or if Chief Engineer Delafield didn't bother to ask their opinions on the matter. There was already a lighthouse on Alcatraz Island. Perhaps it was less an engineering issue and rather that the two lighthouses so close together, perhaps due to their positions relative to the main channel, would have been too confusing?

My family ama my wife's have been long time residents of San Francisco, but this explosion happened before even my great grandmother was born in 1879, although I'm sure her parents knew of this event. Great-grandma had many stories, including leaving her house and living in Golden Gate Park during the fires following the great earthquake (the house survived the fires, was the only house remaining on the block, and survives today on Commonwealth Avenue). There are other family stories of herding cattle from the Midwest to feed miners in the goldfields and gold mining in Colorado, but this explosion story would standout as a singular event.

    True but with several other major rocks and ships getting bigger and needing more room for maneuvering they likely said, screw it, we have the funding. Almost in a line you have Blossom, Alcatraz, Harding Rock plus the Alcatraz shoals and I think Arch rock too. Just going from memory. So you are not just avoiding an isolated rock. More importantly the main anchorage around the point to the sheltered water along the SF waterfront and the route to Oakland means you need to turn the corner there without hitting the rock. With stiff winds and strong currents and no tractor tugs (or almost no tugs at all) in that time frame this was an issue. You can't just go real wide because then you have to worry about Yerba Buena and the shallow water to the east of it. The photos he used point out the fact most ships were still sailing vessels and square rigged at that so not very maneuverable at all.

With electric lighting, basically do away with night. Build ships powered by steam and large enough to be impervious to storms, hence not at mercy to weather. Build dams allowing the arid West to be inhabited and agricultural. Over that century or so we could see this with almost everything, every industry, every human activity, every aspect of life. After that (starting in the 1970s) we started to realize that maybe this was having some adverse effects on the environment (something nobody cared about before) and our own quality of life, leading to a mindset of trying to reduce impacts and finding ways that working with rather than against nature might be more beneficial.
