The Tasmienne Monument with the Coyote Creek in the back.

Decode a Mysterious Plaque – Coyote Creek, San Jose

Metcalfe bridge, Coyote Creek Trail San Jose.

The other day I parked at the Coyote Creek Lake parking lot and walked south over the Metcalfe bridge. The paved trail is part of the Ridge Trail and also part of the National Recreational Trail system. You can bike all the way to Morgan Hill. A few more steps after the bridge you’ll see a plaque on the right. Covered in dirt, but still visible are 0 and 1s. On closer inspection the words Santa Clara Valley appear on top of the binary code.

The Tamienne Monument, with Santa Clara Valley written on it.

I found the Tamienne Monument, or, as some websites also call it, The Center of Santa Clara Valley. This marker is not monumental at all. The plaque can be overlooked. The binary hints to Silicon Valley, the Tamienne reference suggests a misspelling of the Tamyen people who once lived in the Valley.

There is no acknowledgement of the creator and it is not listed in the public art repository of San Jose. For the binary it is less mysterious, I can spoil this for you:
