House of The Velvet Ash
Like other riparian trees of the desert, velvet ash is NOT adapted to
an arid climate at all since the leaves have no mechanisms to prevent water
loss. If the roots did not have access to permanent moisture, the trees
would quickly die.

This stream-side habitat represents a final retreat for velvet ash and
certain other riparian trees. Several million years ago, during the
Tertiary epoch, the region's climate was substantially moister than now.
Velvet ash, Fremont cottonwood, netleaf hackberry and Arizona sycamore
belonged to a great deciduous forest that blanketed the valleys and hills.

Now, forced to survive under extreme conditions, velvet ash is restricted to
riversides and stream-beds.

This photo was taken along the West Fork of Oak Creek Trail north of Sedona, Arizona.

This is Coconino sandstone. When the light
shines a certain way, it glows a fantastic colour.

This rock is also seen at Arizona's Grand Canyon. The Coconino sandstone of the Grand
Canyon consists of petrified sand dunes that were piled up by the wind.

Coconino sandstone is nearly pure quartz in
composition, which actually "catches" the light and assists in its "surreal" coloration.
