A black iceberg photo is going viral today surpassing 1 million views since it was posted to Reddit on Friday.

The photo shows a white and a black iceberg next to each other photographed during the day. The photo was posted by Reddit user Rundboll who did not elaborate on it. However, it appears to be taken in New Zealand.

Although black icebergs are not as common as white icebergs, there is a place known as the "home of the black icebergs" in New Zealand called Tasman Glacier Lake. A video posted on YouTube by self-described travel writer as he explores the lake, shows at least ten of those type of icebergs on the lake. (Watch the video below.) The exact same picture posted by Reddit user Rundboll on Friday appears on the "Tasman Glacier Lake Walk" topic page of travel website www.rankers.com.nz.

There are also blue, green and brown icebergs or a combination of this colors, according to The Canadian Encyclopedia. "Black icebergs are 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," according to the encyclopedia.

Other Reddit users explained how a black iceberg may be possible.

"Black icebergs are more dense than white or clear ones because they usually come from underneath the water where the pressure compressed it. It's color can also to attributed to some of the sand and rocks it picks up from rolling around underwater," user bmbyal wrote.

But one user who claimed to be a geologist blasted this theory.

"As a geologist, let me just say that your comment is completely false. This ice was formed on land under intense pressure from overlying ice and snowpack. The color is from silt entrained by the ice-- silt that can be scraped off of underlying rocks (on land), or can come from rocks/debris that falls onto the ice or is scooped up into the ice and then crushed as the glacier continues to flow," user sackungfu wrote.

However other users got creative with their posts. Some posted photos of blue icebergs and one of them posted a photo which he called a green iceberg, but the photo was the head of an iceberg lettuce. Another user wrote "I see your black and blue icebergs, and lower you an ice cube," and posted a photo of rapper Ice Cube's head on water.
