Japanese Dry Stone Walling

Rather more on-topic is this video. The footage is from the Stone Foundation’s January workshop and symposium. 14th and 15th generation Japanese stone masons came to California to demonstrate their traditional method of dry stone castle and wall building, and to supervise the construction of some ramparts at a park in Ventura. Most noteworthy in the technique is that the walls are battered with a subtle arch/concave shape for structural stability and that each of the structures has a ‘mirror stone,’ an especially large stone meant to reflect the strength of the builder or owner. The caption says the video is a documentary in progress, but I like it as is; it’s not fast-paced, but that’s appropriate for a stonework video, and there’s some good footage of rock shaping.

The Stone Foundation has an article about the project with info and photos. The Ventura County Reporter did a writeup with a slideshow, and the Ventura County Star put video footage in theirs. I’ve never been to any of the symposiums, but I know a few people who have, and they speak really highly of them. Looks like it was pretty cool.

Arizona Flagstone

The corollary to the East Coast Connecticut Blue, is our West Coast Arizona flagstone. It’s sort of the ubiquitous, default flagstone of Bay Area gardens, but I’m always happy to use it. It’s easy to work with, and I like the color range, with each of the colors having a slightly different feel. Oak is the hardest; Buckskin and Peach are the nicest to work with; Sedona Red is the lowest quality, the one to avoid.

Peach is probably my favorite, though in the Bay Area it tends to gray over time if it doesn’t get a lot of sunlight and air circulation or if you don’t put a sealer on it. I showed the photo of this patio once before, but here are a couple of more photos. The plants have really filled in around it.

After Three Years

After Three Years

The Pacific Wax Myrtles are eight feet tall now, three years after planting as five gallons. I think they’re going to lose the race with the workers constructing the McMansion next door, but they should provide a good screen fairly soon.

Last month I went back and built a second patio with the leftover stone and another new pallet of stone. The cinder blocks are new veggie and flower beds that the clients are building. I think the block will eventually get mortared and stucco’ed.

Sedona Red

Sedona Red is by the far the softest, weakest, crumbliest of the Arizona flagstones. My parents house was the only place I’ve ever used it, and I hope to never use it again. Fortunately, the patio is mostly to be seen and is rarely walked on, so there haven’t been problems with cracking. This is a photo of it in its first year; I had some nice photos of it this spring with a ton of crocuses blooming, but those photos were lost when our laptop got stolen. If the crocuses do their thing again next spring, I’ll swap this photo out for a better one.

You don’t really want sandstone to be this striated; it’s often a sign of how weekly bonded the layers are. With other Arizona sandstones, the striations are not nearly as distinct.

I have a few more photos of palleted stone below, similar to what you would find at the stoneyard page, but not so tiny. Actual colors of course vary. (more…)
