Qanats for the Okanagan

Late afternoon in the grasslands. November. Light’s almost gone. Cloud everywhere. Nothing much to look at here. Zzzz.

Or, maybe there is. Have a look just down the trail. The guys building a new townhouse kind of, well, absented themselves for a couple months, but they’re back at work, hurrah, and look what the grass thought of that, eh.

So, rather yellow, yes, and shy on proteins, yes, but coming in nicely at the edges before they tilted that heat-absorbing shield back up. With that in mind, let’s look at our hillside again.

See that scree running down from the head of the hill there? It forms an underground river, a kind of qanat, such as the watercourses of ancient Arabia, the Gobi Desert, North Africa and the Roman Rhine, with water, slight as it is, protected from evaporation by a cover. And there’s more! Look how the grasses and sage are moving in from the side, soaking up the heat stored in the rock and harvesting it, just as this grass…

… did with its metal shield. And what have the construction boys been up to? Ah, very important high tech environmentally conserving work, all according to regulations, and, dagnabit, the seeded grass cover washed away, the dust fencing collapsed, and water wreaking its havoc, as it will, and all blamed on, you know it, yes you do, global warming and a shift in weather patterns to try the patience of St. Francis and all foundation forms contractors.

Ah, but is it terribly wrong? Is that not the first step towards building a qanat? Don’t you have to wash the soft soils downhill, to make a seedbed down there for the coming water? And don’t you have to dig a channel to collect rocks — in this case, from side erosion — to form the qanat? Why, yes! And would not plants, over time, fill in the sides of the channel, bulking up on the sand they’ve caught as it drifted across the hill, and slowly building the soil up, as they have in the image below?

Perhaps trying to do it on the fly, all at once …

… is a good effort, but, you know, this one …

… with grass instead of poly cloth and rocks instead of tiny little grass seeds in a pap of recycled newspaper, is going to cost less in the end? I mean, it doesn’t need maintenance, or but thickens over time. Besides, it has room for snakes, and you like snakes, right?

Hmmm… maybe not ants. Well, I’m sure they’ll sort it out. And as you walk up the hill harvesting this side growth, what is there for you, to make it easy? Why, a staircase of stones! Beats slogging up the muck.

You’re just going to find ants on the muck, and they’re not half so fun as snakes, or what washes down from the muck and can feed you.
