There’s an interesting sight on the Don River north of Pottery Road. Just across the river from Cottonwood Flats, a series of icicles dripping from the hillside create an ice curtain that curves for about 200 metres along the river bank.
Although a few of the individual icicles can be traced to water channels that trickle down from the top of the hill, most seem to sprout from the hillside just a few metres above the river:
Given the extent and uniformity of the ice, my guess is that most of it comes from groundwater seeping into the river at this location.
Beautiful. Reminds me of the “ice curtains” that come out of the escarpment in Hamilton (and I presume anywhere along the way).
