Cottonwood Gulch (Reflection Can.)
Cottonwood Gulch (Reflection Canyon) is just
over the wall in the foreground. The San Juan River joins the Colorado
in the lower left corner of the picture. Hidden Passage is in the center
of the picture about a mile downstream from Cottonwood Gulch. Music
Temple is across the Colorado from Hidden Passage and a little downstream.
Its canyon is just behind that tall wall (the tallest in the Glen) on the
left bank. The entrance to Mystery Canyon is a couple of miles downstream
from Music Temple and on the left, near the edge of the picture.
|Lower Cottonwood Gulch. A deep canyon,
but not particularly narrow.
These graceful entrenched meanders are not
deep by Glen Canyon standards, but they are photogenic. The cover
of Eleanor Inskip's, Glen Canyon Before Lake Powell has a photo
of Reflection Canyon very similar to this one. The July/August, '06
issue of Audubon Magazine shows this canyon as reexposed by the
lowering of Lake Powell by drought.
This canyon is quite deep
by ordinary standards: See the person in the picture below for scale.
The ridge dominating this picture is the small
ridge in the lower right of the aerial photo above. The photographer
is under the dark overhang in the far right center of the canyon and shooting
so as to take in in both upstream (left) and downstream (right).
At the far right in the downstream direction note the man waving his arms.

From farther upstream. The lower end
of Cottonwood Gulch is now flooded by Lake Powell, as is the San Juan River
in the upper, center-left of the picture. The high wall on the right
was the highest wall in Glen Canyon. It overlooked the confluence of the
Colorado and San Juan Rivers.
One of the short swimming sections in
the lower part of Cottonwood Gulch.
