Global warming, California style.

"[T]he tongues of ice creeping down [California's Mount] Shasta's volcanic flanks give the solitary mountain another distinction. Its seven glaciers, referred to by American Indians as the footsteps made by the creator when he descended to Earth, are the only historical glaciers in the continental U.S. known to be growing."

That's fine, but is there such a thing as an ahistorical glacier?

Ah, yes, a glacier formed in a crater formed by the eruption of Mount St. Helens in 1980.

Saint Helen? Apparently, she's the patron saint of "archeologists, converts, difficult marriages, divorced people, and empresses". Link.
