"...we go around a great bend to the right, five miles in length, and come back to a point within a quarter mile of where we started. Then, we sweep around another great bend to the left, making a circuit of nine miles, and come back to a point within 600 yards of the beginning of the bend.

In the two circuits we describe almost the figure 8. The men call it a 'bowknot' of river; so we name it Bowknot Bend. The line of the figure is 14 miles in length"

-Maj. John Wesley Powell, The Exploration of the Colorado River and its Canyons
