Very nice! I hope to go iceberg watching when I can get to Newfoundland in the right season. The one in the above photo is said to be from Alaska.

I have been to New Foundland twice. First in Oct 62 and though it was still very warm in GA where I had flown out of, it was chilly in New Foundland. Bleak landscape too.

Coming back from Frankfurt to land at McGuire AFB, we also stopped at New Foundland at the end of January 64. Snow was way up to the roof tops of buildings. We had to walk through a snow tunnel to get inside as they refueled the A-F passenger airplane.

I don't have good memories of New Foundland.

I wonder where in AK some sort of Berg would be black?

I am still enjoying that photo of the black berg.

Appearance
Most icebergs are white except along freshly calved ice cliffs, which tend to appear blue. Others may appear green, brown or black, or combinations of these colours. These icebergs have usually rolled over, exposing basal ice, or have emerged from below water level. The various colorations are caused by differences in density, air-bubble content and impurities. For example, black ice is of high density and bubble free; dark layers indicate the presence of rock materials derived from the base of the parent glacier. Occasionally, rocks may be found on the original upper surface of the iceberg. As the iceberg melts, these materials precipitate into marine or lake sediments.

I still wonder where that black berg came from.

Really.

Can anyone pinpoint the birth location? Please don't say alaska. If you say that, roll out your map. Alaska is enormous.

Due to a lot of volcanic action at Iceland, were I to guess, I would guess it came from there.
