"Ancient River Found in Antarctica After 34 Million Years"

Scientists have discovered evidence of a 900-mile-long river that flowed through West Antarctica around 34 to 44 million years ago, before the continent became covered in ice. This ancient river, similar in size to the Rio Grande, suggests that West Antarctica had a temperate climate and was mostly above sea level at that time. The findings, based on sediment analysis from the Eocene period, provide crucial insights into the continent's pre-glacial conditions and the onset of major Antarctic glaciation.
