This week’s image (a panorama) comes from Utah, not far from Mexican Hat:
This formation is called the Goosenecks — it’s a stretch of the San Juan river where river meanders have eroded straight down over millennia (the official term is “entrenched river meanders”). As a result, the canyons are now more than 1,000 feet (300 m) deep, such that the walls separating opposite sides of a loop create thin natural land bridges. The meanders are so tightly wrapped (the river originally worked its way lazily across a plain here, before the plateau was uplifted) that a raft would travel for 5 miles along the river while only progressing 1 linear mile toward Lake Powell.
From here, the San Juan flows in a relatively straight fashion to its confluence with the Colorado river.
