British Columbia?? I’m losing confidence in the hypothesis that this expression is a northeastern US/eastern Canada thing.
My late mother-in-law of Scottish descent, who grew up on a small farm near Cape Cove (Gaspé Co., Quebec, Canada – http://goo.gl/maps/NGnK5) in the 1930s and 40s (as well as her sister) would commonly use the word ‘glib’ not as an adjective meaning slippery, but as a noun meaning a slippery surface, as in: “After the ice-storm, the sidewalk was a glib of ice.” She also frequently described her daughter as being “stubborn as a pig on ice,” but that’s another story…
 Use of ‘GLIB OF ICE’

“We got the snow that night and the next day-a foot at least and more at the bottom of the driveway where the snow plow likes to store the extra. Life, the rest of the month, went on in the midst of storms of snow, then rain, then ice pellets, then ended with a nice flourish as the driveway, in country terms, became a ‘glib’ of ice. The glib continued to make going up and down the driveway quite interesting until a good friend came by early in February with some sand from the government garage. More sand, left sometime later by another neighbour after the first lot had been vanquished by another glib, served to foil several later glibs and the question seemed to be whether the sand or the glibs would run out first. As in the opera, the good guys won.”

“Black ice has two meanings on P.E.I. [Prince Edward Island] On a highway, it’s a thin, dangerous coating that’s almost invisible. On a lake or pond, it’s a layer so thin and transparent it looks dark. Black ice is thinner than Glib or Glibby Ice, which is very hard, smooth, and slippery. Glib Ice is perfect for skating.”
*Thomas, William Beach. 1947. In the Low Country. The Observer (London, UK). 2 March 1947, p. 2
“What specialists in ice the Fen people are! They speak of anchor ice – a curious formation of ice in two layers – of “glib” ice, or black and white and snow ice, and traverse it, even if it has become rib ice, on pattens, a better word than skates as the bandy they delight in is a better word than ice hockey.”

“Often have I keenly relished a long homeward stroll [through Copenhagen] on such a night, with the strong-handed wind pinning my dear old cloak tightly around me, and propelling me swiftly along the slippery street, which oft presents at night one surface of glib ice.”

“In some parts of the place the hard coating of ice which was formed during the early winter had not yet been destroyed and on Monday the young people were coasting down hill on the glib ice, which made the sport very enjoyable.”
I think the term “black ice” is widespread among English speakers. My mother from New Jersey always told me to watch out for black ice in winter. Black ice, of course, was very dangerous because it was so thin it was difficult to see. Therefore, you had to be careful when walking or driving in sub-zero weather even if the path or road ahead looked clear, because it might not actually be clear.
