in Nehalem Bay Park near Manzanita, Oregon.
Here’s an excerpt from the Cannon Blog at Oregon State Park website:
“Posted June 20
Been a while between updates, so here’s a catch-you-up.
The next public viewing is July 5, from 1-2 p.m.
Carpool or find some other way to reach the park … this is a holiday weekend and parking will be tight.
The viewing is in the Nehalem Bay State Park maintenance yard (there will be signs … it’s just inside the entrance to the park).
We had an exciting time in May. Oregon Public Broadcasting produces TV episodes for the nationally-broadcast show History Detectives. They’re producing a show on the cannon with the question: Are these from the USS Shark? To help gather more information on their origin, the show arranged for some x-rays of the cannon. Fuji Corportation donated time on one of their portable x-ray machines, and a company called PSI from Portland volunteered their time as industrial radiographers. It was a challenge to get some good, clear images, but they did produce a couple. It was cool to watch them in action, and the x-rays give us a peek beneath the heavy, crusty shell (made of sand and iron, sort of a natural concrete).”
