Cambridge

Department of Applied Mathematics and Theoretical Physics

I went to England in 1999 to see the total eclipse of the sun (it was cloudy). But while I was in London, my brother and I spent the day going up to Cambridge where we visited the University and I was thrilled to come upon the Department of Applied Mathematics and Theoretical Physics … one of the hangouts of Stephen Hawking.

We later walked over to the river Cam and I poled a punt (skiff? … ?) on the river. My brother was a little nervous with my poling … not having been with me during any of the hours I had spent poling my canoe. This was lots easier … not nearly as tippy. It was fun to pole under a bridge on the Cam.

Upstream and Downstream

Upstream

These photos were taken from the Graves Creek Bridge on the East Fork Quinault trail in the Olympic National Park. I thought the difference between the two was interesting … you just wouldn’t likely think the photos were taken the same spot. The difference between the two ‘sides’ is purely a result change in gradient … there isn’t any dam or blockage below this point on the creek.

Bridges: Open or Closed?

Bridge Opening For Navy Ship

One of the facts of life living on the north half of the Olympic Peninsula is that access to and from major population centers (think shopping and medical appointments) relies on crossing the Hood Canal bridge. In the case of Navy vessels (both submarines and support ships going to/from the Bangor Naval Base (think Trident Nuclear Submarines). Depending on the time of day, the delay can be easily close to an hour. And longer delays are possible during stormy weather, when the bridge is opened to minimize the strain of water being pushed against the span. Then the roadway is closed until the weather moderates.

But my question is: when do you call the bridge “open” and when do you call it “closed”? To me, when the bridge is open, the roadway is closed. But I’ve had conversations with people who say the bridge is closed … meaning that it is open for highway traffic … and other conversations where “the bridge is open”, meaning that it is open for highway traffic. Having grown up in Seattle, with its numerous draw bridges, I’m used to the perspective that when a bridge is open, it is open for boat traffic.

Are you mixed up yet?

Unexpected Delay

Upstream – Downstream

Upstream from the Bridge at Six Stream

These two photos are taken from the middle of the bridge across the North Fork Skokomish at Six Stream, which comes into the North Fork just south of the bridge. The bridge is just about 6 miles up the North Fork Skokomish trail …

The Six Ridge trailhead is just at the upper end of the bridge … and that trail is one of the most rugged, least traveled and least maintained in the Olympic National Park. One that I have contemplated hiking in the past, but never got around to. (that’s what happens when you have a full time job)
