familiar with their nature. On parting he remarked,

"Well, boys, you are going to tackle a mighty hard proposition, but
I'm sure you can make it if you are only careful. But look out and go
easy."

Wolverton was no novice, speaking from much experience in bad water,
and we were greatly impressed by what he had to say.

Five uneventful days were spent in Labyrinth and Stillwater canyons,
through which the Green peacefully completed its rather violent
descent. In the upper end we usually found rough water in the canyons
and quiet water in the open sections. Here at least were two canyons,
varying from 300 feet at their beginning to 1300 in depth, both
without a rapid. The first of these was Labyrinth Canyon, so named
from its elaborately winding course as well as its wonderful intricate
system of dry, lateral canyons, and its reproduction in rock of
architectural forms, castles, arches, and grottos; even animals and
people were represented in every varying form.

Our Sunday camp was beside what might be called a serpentine curve or
series of loops in the river. This was at the centre of what is known
as the Double Bow Knot, three rounded loops, very symmetrical in form,
with an almost circular formation of flat-topped rock, a mile or more
in diameter in the centre of each loop. A narrow neck of rock connects
these formations to the main mesa, all being on the same level, about
700 feet above the river. The upper half of the rock walls was sheer;
below was a steep boulder-covered slope. The centre formation is the
largest and most perfect, being nearly two miles in diameter and
almost round; so much so, that a very few minutes are necessary to
