Cottonwood Shade in Pima Canyon

The cottonwood’s deep roots draw water from a mountain stream.

Looking back down Pima Canyon on a spring morning plenty of green under the unrelenting sun.

A large Fremont’s Cottonwood Offers shade and protection along the Pima Canyon Trail.

In the shade, a grapevine, offers a vain promise of grapes.

The cottonwood’s deep roots draw water from a mountain stream.

Native Americans in the Western United States and Mexico used parts of Frémont’s cottonwood variously for a medicine, in basket weaving, for tool making, and for musical instruments. The inner bark of Frémont’s cottonwood contains vitamin C and was chewed as an antiscorbutic – treatment for vitamin C deficiency. The bark and leaves could be used to make poultices to reduce inflammation or to treat wounds.

The Pima people of southern Arizona and northern Mexico lived along Sonoran Desert watercourses and used twigs from the tree in the fine and intricate baskets they wove. The Cahuilla people of southern California used the tree’s wood for tool making, the Pueblo peoples for drums, and the Lower Colorado River Quechan people in ritual cremations. The Hopi of Northeastern Arizona carve the root of the cottonwood to create kachina dolls.

Cactus Blossoms in Pima Canyon

Delicate buds develop into a flower, and then, into a cactus tuna

Eight New  Blossoms

Here are 8 flower bud growing from one cladode (pad).  There is a 9th bud on a second cladode.  What is interesting about these pads are the needle shadows.  Although thin, each provides some protection from the sun.

Cactus Closeup

This delicate bud will develop into a flower and, then, into a cactus fruit (in spanish, tuna).  The fruit retains those tiny spines, called glochids, which detach on the smallest contact.  The pads are also covered with them.

Prickly pears are known for growing into thickets.  The Cuban government created a “cactus curtain” of prickly pears around the Guantanamo naval base in the 1960’s, to prevent Cubans from escaping to refuge in the United States.

Cactus Flowers

Look closely at the anthers of these flowers.  Each curls over when touched, depositing its pollen.  The habit of prickly pears to grow together in thickets mean there are clusters of blossoms in springtime.

Flowering Saguaros in Finger Rock Canyon

Some Fallen, Some Blessed

My visit to Finger Rock Canyon of the Santa Catalina Mountains filled two mornings.  On the first morning, the subject was the lower canyon as morning light filtered over the eastern ridge.

Early morning to the north / northwest looking over a 20-foot fallen Saguaro Cactus (Carnegiea gigantean), toward lower ridges of the Santa Catalina Mountains.  The saguaro is among a stand of healthy fellows, some with new growth and flowers on the tips of arms and main columns. This giant must have grown over rock through 60 years.  It was brought down when the roots weakened.  Specimens that are more reliably rooted can live to 200 years.

A clump of brittlebush shrub (Encelia farinosa) grows from the same rock.

Pima Canyon is the next over, behind that near ridge which provides similar shade.  Unlike Finger Rock Canyon, the Pima Canyon trail follows the western cliff and loses the shade much sooner.  During our three-week trip, my wife, Pam, and I visited Pima in our first week.

These photos were taken between 6:20 and 7:00 am.

Along the trail I noticed a multitude of buds on the tip of selected saguaro arms.  In a previous blog, there’s a photo of this same saguaro in the shade.  The following series captures the one blossoming top just as the sun passes over the eastern, shadowing, ridge.

The same saguaro, two minutes later…….

Here is a portion of the saguaro forest, around 7 am with the lower canyon filled with light.  There are a few foothill homes with west and southwest Tucson.  The Tucson Mountains are in the distance.
