UC Davis Research Team Shares Experiences From Recent Field Season in Antarctica

The McMurdo Dry Valleys don’t look like they belong in Antarctica. Largely devoid of snow, the landscape is mostly dirt and rock. When explorer Robert Falcon Scott trekked the area in 1903, he referred to it as “the valley of the dead.”
