Photos of the exploratory shaft being dug in preparation of Purple Line Extension construction

My colleague Dave Sotero and I had a chance today to visit the exploratory shaft being dug as part of the Purple Line Extension subway project. If you’ve been to LACMA recently, you may have noticed the big wall covered with Metro posters across the street. That’s the exploratory shaft.

It’s quite a feat. The shaft is already 65 feet deep and is being dug to learn more about soil conditions in the area and validate what is already known. The work is an important step in preparing for station excavation and tunneling for the subway.

Quite a few fossils have already been found, including clams, sand dollars and parts of the cone and seeds for digger pine trees. While we were there, in fact, a rock was found that appears to have a sea lion skull within it that is perhaps two million years or more old. Metro is working with the Page Museum at the La Brea Tar Pits to identify and preserve the fossils found.

We’ll post lots more about the shaft soon. In the meantime, Channel 7 should have a segment on the work being done as part of tonight’s newscast. See KABC 7’s story here.
