Now a second Idaho landscape is giving scientists insights into extraterrestrial geology. The amphitheater-headed canyons of Malad Gorge bear a strong resemblance to amphitheater canyons of Mars, and one NASA-funded study concludes that both landscapes may have formed under similar circumstances. The resemblance between canyons on Mars and Idaho is illustrated in this pair of images. The top image shows Woody’s Cove, one of two amphitheater canyons in the Malad Gorge in south-central Idaho.
