Municipal snow dump site was accessible without any barrier or fence, so I was able to do urban snow-boulder rock climbing in February.
The time-lapse video shows that my geological engineer/exploration geologist daughter Évelyne climbed all the way up to the top of the snow boulder, but I gave up because fresh snow was too slippery. The snow under the fresh snow had solidified, so it was slippery. The fresh snow didn't give us a good grip, but it was helping more than hindering.
Snow was almost completely gone in May except for minuscule remnant that I was able to conquer.
