Ammonites in Seattle

Last night I was fortunate to give a short presentation to the Cephalopod Appreciation Society. I wanted to follow up that talk with a guide to where to see ammonites in Seattle. Here’s the skinny.

The rock:
155 million year old Treuchtlingen Marble – It is actually a limestone because the rock has not been metamorphosed. During the Jurassic Period when dinosaurs roamed the land, a shallow sea covered much of Europe. Many critters from that sea are now preserved in the tan to gray limestone. When the animals died they settled to the bottom of the sea. The most common fossils are sponges, bottom dwelling, filter feeders that formed small mounds. They may be round, straight, or irregularly shaped and are darker than the surrounding limestone. The ammonites are the largest fossils. They are coiled-shell animals that resemble a top down view of a cinnamon roll. The biggest ones in the German limestone are about five-inches across, whereas the largest ones that ever lived were six feet wide. Ammonites swam the seas from about 400 to 65 million years ago, going extinct, along with dinosaurs, at the K-T boundary. Their modern relatives include squids, chambered nautiluses, and octopi. You can also find another squid relative, belemnites, which look like a cigar. They are dark brown and somewhat shiny.

Where to see ammonites in Seattle:
1. Cherry Hill branch of Swedish Hospital, formerly Providence Hospital (on East Jefferson St. between 16th and 17th Avenues) – Fossils are in the main building in the stone that makes up the floor.
2. SeaTac Airport – A/B Food concourse, walls are covered in Treuchtlingen.
3. Grand Hyatt Hotel – 7th Avenue and Pine Street – Floor of lobby and into hallway/lobby of conference rooms on ground floor.

Mikado Street in Seattle

I have read in a variety of books, articles, and web sites that one of the earlier signs of the presence of Japanese in Seattle was the street name “Mikado Street.” The reference, I believe, is to Augustus Koch’s 1891 Bird’s Eye View of Seattle, which includes the street on it. Below is the map and here’s a typical line about the street. “Their [Japanese] influence can be seen all the way back to the late 1800s, when Dearborn Street was named Mikado Street.”

Although this sounds credible, I don’t think it is correct to attribute the name to the presence of Japanese in Seattle. Mikado Street was named in 1886 as part of what is known as Terry’s Fifth Addition to the City of Seattle. Terry refers to Charles Terry, one of the Denny Party, or founding families of Seattle. He had owned large sections of Seattle, which his descendants later platted. This particular plat of Terry’s estate was planned by Erasmus M. Smithers (what a wonderful name) and Franklin Matthias.

Within the legal description of the plat, Smithers and Matthias describe that all of the streets but one are prolongations of preexisting streets. Only Mikado is new. Nowhere do they state the origin of Mikado. This was typical, that the people planning the plat would either continue preexisting streets or come up with names for the new ones.

The main reason I think that Smithers and Matthias didn’t choose Mikado for its connections to Japanese immigrants into Seattle is that there were fewer than a dozen Japanese living in Seattle in January 1886 (Issei: A History of Japanese Immigrants in North America). Plus, I cannot find any connection between Japan and Smithers and Matthias.

But 1885 was the year that Gilbert and Sullivan’s opera The Mikado debuted in London. It quickly became hugely popular. H.L. Mencken later wrote that by the end of 1885, 150 companies had performed the show. In December 1885, the Seattle P-I reported on the “Mikado craze,” with Mikado rooms being built in Manhattan mansions. Perhaps more relevant to Seattle’s story, on January 8 (10 days before Smithers and Matthias filed the plat), The Mikado opened at Frye’s Opera House in Seattle.

Of course, this is circumstantial evidence but it does seem more likely that Smithers and Matthias chose Mikado for the popularity of the opera than for an acknowledgment or honoring of the Japanese in Seattle. If anyone has other  ideas, I would be happy to hear them.

In 1895, the city of Seattle changed Mikado Street to Dearborn Street. Section 276 of Ordinance 4044 (which changed more than one hundred street names) states: “That the names of Alaska Street, Mikado Street, Modjeska Street, Cullen Street, Florence Street and Duke Street from Elliott Bay to Lake Washington, be and the same are hereby changed to Dearborn Street.”
