A cold cold canyon - 4,500 years a-cooling.

Not sure how the creationists will react to this news but no doubt they'll put some sort of twist on it. A subglacial Antarctic canyon, bigger than the Grand Canyon, has been found. No doubt Prof. Andy McIntosh will explain how so much ice has built up in and over it in the 4,500 post-flood years. (Its formation won't be a problem for him, since he thinks that the American version could have been gouged out in a matter of hours.)
Scientists probing the icelands of West Antarctica have discovered a subglacial pit that is deeper than the Grand Canyon.

The researchers were charting the Ellsworth Subglacial Highlands-an ancient mountain range buried beneath several miles of Antarctic ice-by combining data from satellites and ice-penetrating radar towed behind snowmobiles and onboard small aircraft.

The project uncovered a massive subglacial trench, or valley, that is up to 1.9 miles (3 kilometers) deep and more than 15.5 miles (25 kilometers) across. For comparison, the Grand Canyon is 1.13 miles (1.8 kilometers) deep at its deepest point. In places, the floor of the subglacial valley is more than 6,500 feet (2,000 meters) below sea level.

"It's a huge privilege to be able to reveal another piece of the jigsaw puzzle that is the surface of our Earth," said study team member Neil Ross, a geophysicist at Newcastle University in the U.K.

Scientists aren't sure exactly when the valley was created, except that it was tens of millions of years ago. "What we do know is that Antarctica has been glaciated for at least 34 million years, and during this time the ice in West Antarctica would have oscillated in size from the small ice-field conditions ... to the large ice sheet that we see today," Ross said.

The team speculates that the valley was initially formed when a river exploited a geological weakness, such as a geological fault. However, it was glaciers that did the hard work of deepening the valley.

"A river cannot incise a valley below sea level. [This type of deepening] needs erosion by glaciers," Ross said.

Last year there was a similar discovery in Greenland. I think it was flagged on this forum under News.

As far as I recall no YEC touched it with a bargepole. I suppose it's easy to ignore since you cannot directly observe it with your own eyes due to it being underneath metres of frozen snow.
