Snow Patterns

When we bought this house, the deck was in bad shape and had to be replaced. Unfortunately, the surface of the deck that was installed in its place did not last as long as one might have expected. The cedar decking was installed with a modest gap between the boards, so that air could circulate to help the boards from becoming water logged, which leads to rot. The notion was that, as the boards dried further after installation, the gap between the boards would increase a little. Unfortunately, things did not go as planned. There was so much shade on the side of the house with the deck, that the cedar never got as much opportunity to dry as had been anticipated. A couple of years ago, when we had to replace the deck surface, we were faced with the question of how far apart to space the new boards. If we didn’t leave sufficient space between these boards, we would soon have the same problem all over again. We decided to be cautious, and left a decent-sized gap between the boards. That has worked out well – the boards appear to be staying dry, but the gap is not so large as to be a problem when walking/standing on the deck.

When we get a gentle snowfall of a few inches, arriving without appreciable wind, the snow that lands in “the gaps” simply falls through, leaving what strikes me as an interesting pattern. Here is a shot of our deck this morning, just before I shoveled:
