There's an old myth that Inuit have many names for snow. I've found a few of my own this winter. Feel free to add!
Overflow: Runoff forced from frozen rivers and streams during thaws or because of ice pressure. It covers paths around the stream and can create dangers. I've seen standing water on these formations even when the temp is well below freezing.
Terminal Moraine: A buildup of snow and ice that blocks all progress.
Lateral Moraine: A buildup or berm of ice and packed snow along the side of a road or path that will upset balance if the front wheel touches it.
Chunder: Large blocks of black ice and frozen gravel kicked up into bike lanes and paths by large snow plows.
Chop: Mix of ice furrows, snow and gravel that doesn't upset balance but makes the ride seem like taking a ship through heavy chop.
Flour Snow: Fairly fresh snow that's been kicked up by cars into a dry powder that resembles flour. It can pack on top of black ice, then slide off suddenly.
Biscuit Dough: Flour snow that's been coated with oil and crud from cars. It feels like and resembles biscuit dough after the butter is in. Often has a yellowish hue. Can conceal ice ridges, chunder and ice traps.
Man Hauling: Having to push your bike when the snow gets too deep and soft to pedal further.
Pressure Ridge: Formation of thick ice ridges that forms after Chinook winds or where overflow meets existing ice packs.
Freeway: Any patch of smooth trail or road you manage to find.
