Last seen in 1962

I have only ever seen this particular view of one of the waterfalls in Johnston Canyon on two occasions, despite having climbed the canyon regularly between 1954 and 1971. The main hiking trail up the canyon is a bit back from the edge over the roof of this cave, and you used to have to climb down through the forest to reach this spot.  It must be more accessible now, because even the Google Camera has been here!

Fourth Revolution Haiku

Larch Valley


This is a computer-abstracted version of a painting that was based loosely on some other people’s photographs taken from Sentinel Pass above Larch Valley. I’ve never been up there myself, because of a grizzly bear warning posted at the trailhead at Moraine Lake (plus it’s a really long climb.)  

The haiku is advocating a larger role for direct current on our power grids, as DC is required by many end-use devices such as digital equipment, solar PV, storage batteries, electric vehicles.  The fourth revolution is, of course, the fourth industrial revolution – intelligent automation, artificial intelligence that enables robots to learn and communicate with each other, machines that can make multiple products and customize each one, software-driven systems.

Climate change preparation

The Oilsands

Canada is gradually improving its ranking in environmental opinion polls, but we’re still subject to some derision, focusing on the Alberta Oilsands, which critics refer to as ‘tarsands that produce the world’s dirtiest oil.’
They may be right, but I think if we paid higher carbon taxes we could pay for whatever research it takes to clean up this energy source. And this would be far better than going to war over oil in the Middle East or using food to make biofuels.

In the meantime, I thought I’d present this ‘blot on the landscape’ as a ‘cleaned up’ semi-abstract design. As for making sense of the rest of the overlaid haiku, Googling ‘climate change preparation’ will get you over a million results to read...
