Ice oddities

I took a walk through my neighborhood on a cold morning last week. I saw some neat features in the ice.

Adrift On An Ice Pan, by Wilfred Thomason Grenfell

This very short narrative (hardly even a proper “book” in the modern sense of the word) is by the survivor of a wretched ordeal, as the title suggests, off the coast of Newfoundland in 1908. I consumed the audiobook version, as a free download from my public library, and finished it in a single day’s commuting, with time left over for a podcast or two. The deal is this: The …

After the flood

After Passage Creek receded following last week’s flood, I went down to the bridge and the floodplain to have a look around. Here’s a little bit of what I saw… Let’s start at the bridge itself.

Floe Lake hike

Last summer, my wife and I spent some time in the Canadian Rockies. One of the things we did was to take a three-day backpacking trip to Floe Lake, in Kootenay National Park, British Columbia. We picked a rough couple of days for hiking – We got a lot of Canadian Rockies precipitation out there: we got rained on, hailed on, and snowed on during those three days. Here’s our …

Contemplating the IARC-JAXA graph
