Minute of Zen: Gravel on Spider’s Thread

Tuesday, July 13th, 2010

I saw this piece of pea gravel magically spinning in the air behind my house [YouTube].

It was about a foot off the ground then. When I returned later after forgetting about it, my head bumped into the gravel piece. A spider on the roof must have been trying to pull in the thread. I bet he was getting tired.

Rock Study at the Concrete Bridge

Concrete bridge at Duke Forest, October 2007

Last fall, the powers that be at Duke Forest (presumably the Forestry department at Duke) re-positioned the rocks on the downstream side of the concrete bridge as shown in the first image. While New Hope Creek is usually gentle, I couldn’t imagine the piles holding up long during the heavy flow periods. The images below show the same view over the winter.

Though the piles are lost, it’s interesting that the few big rocks held their approximate locations.

Here is a current image. It looks like a new arrangement is being tried.

New Hope Creek Bottom Update

Tuesday, October 16th, 2007

With the drought continuing, a reader asked for an updated picture of the New Hope Creek “subflooring” I showed in August. The boards are completely dry now.

New Hope Creek Bottom

The water is at least a foot lower than before and the small pool in the background is about the only water in that section of the creek. Here is the creek bed away from the dam site.

Bottom of New Hope Creek at Johnston’s Mill

It looks like it’s so dry that the sub-flooring of New Hope Creek is showing through, but it’s really the base of the old dam at Johnston’s Mill Nature Preserve.

Ivy vs. Vinca

Ivy Versus Vinca

Most of our yard is covered in ivy. It makes a nice green ground cover, and we just have to trim it back from trees, beds, and paths a few times a year, which is a lot easier than mowing grass every week. Vinca is a little more insidious, so I try to remove it entirely when it shows up in flower beds.

When I saw some vinca in the ivy a couple years ago, I decided to let them fight it out. I thought the ivy had won a while back, but it must have been a seasonal surge. Now it looks like the vinca is not only holding its own but has spread out within the ivy.

Foreground Removal with Photoshop

Stone Wall original

While walking in Duke Forest, I took a series of photos of this stone wall from slightly different vantage points. The idea was that I could then overlay the images in Photoshop and keep the good parts of each one, removing the foreground small trees and branches.

Stone Wall cleaned

It worked OK once I got the hang of layers, but there were still a couple of problems. Some of the vantage points were too different — I needed to be more careful about keeping the angles parallel. The other problem was that some rock parts were covered in all of the photos, so I had to fill in that area from other parts of the wall.

Bill tells me that’s what I should have done in the first place — just take one photo and use fake/duplicated rocks to replace the foreground material. My way seems more honest, even though the cleaned up image is still a fake.

Backyard Deer

A couple of deer photos from the backyard. They’re pretty brave until the camera comes out.
