Rincon Flame: The Southwestern Paintbrush’s Desert Dance
Step into the Rincon Wilderness with me, where the Southwestern Paintbrush blooms amidst the ancient stones.
Discovery in the Rincon Wilderness
In the embrace of the Rincon Mountains, east of Tucson’s hum, lies the Rincon Wilderness, a tapestry of desert life and geological marvels. These mountains, one of the “Sky Island” ranges cradling the Tucson valley, are less rugged than their siblings, the Santa Catalinas and the Santa Ritas, offering a gentler invitation to explore their secrets.
Happy Valley Saddle’s Floral Jewel
Amidst the rugged beauty of Happy Valley, a hidden corner in the quilt of the Rincon Wilderness, a singular red-orange glow caught my eye. There, among the lichen-encrusted boulders, stood the Southwestern Paintbrush, Castilleja integra, its flamboyant bracts a fiery contrast to the muted greens and grays of its surroundings.
Portrait of a Parasite
This herbaceous perennial, with its soft downy coat, is a paradox, both painting the desert with life and leeching it from others as a hemi-parasite. Its roots, entwined with those of other desert dwellers, tell a tale of survival that’s as old as the hills themselves.
The Brushstrokes of Evolution
Each leaf, narrow and dusted with hairs, speaks to the adaptive artistry of nature, designed to conserve precious moisture. The flowers, with their extended blooming season and generous nectar, court the hummingbirds who dance between the blooms, pollinators in this ancient symbiosis.
A Symbiotic Canvas
The Southwestern Paintbrush, with its colorful allure, draws more than just winged admirers. Its presence among the rocks is a reminder of the complex ecological web of the Rincon Wilderness, a part of Saguaro National Park’s rich mosaic

Ferns, ancient plants with unique reproduction strategies and ecological significance, adapt to diverse environments while contributing to overall biodiversity and human culture.
In the vast tapestry of the plant kingdom, ferns occupy a unique and enduring place. These ancient plants, often overlooked in favor of their flowering counterparts, have a fascinating and seemingly eternal existence that spans millions of years. Ferns, with their lush green fronds and distinctive reproductive mechanisms, offer us a glimpse into the enduring legacy of life on Earth and the remarkable adaptations that have allowed them to persist through the ages.
Ferns belong to the group of plants known as Pteridophytes, which evolved more than 360 million years ago during the late Devonian period. Their evolutionary history predates the appearance of flowering plants, making ferns some of the oldest living organisms on our planet. This remarkable longevity raises the question: how have ferns managed to survive and thrive for so long?
One key to the success of ferns lies in their unique reproductive strategy. Unlike flowering plants that produce seeds, ferns reproduce via spores. These small, dust-like structures contain the genetic material necessary for ferns to reproduce. When mature, ferns release spores into the environment, where they can be carried by the wind or water to new locations. Once a spore finds a suitable environment, it can germinate and develop into a new fern plant.
The spore-based reproduction of ferns is not only ancient but also highly efficient. It allows ferns to colonize diverse habitats, from moist, shaded forests to arid deserts. Additionally, ferns can form extensive networks of underground rhizomes, which are creeping stems that give rise to new fronds. This vegetative propagation further contributes to their resilience and adaptability.
Ferns have also developed a range of adaptations that enable them to thrive in various environmental conditions. Some fern species, such as the resurrection fern (Pleopeltis polypodioides), can endure extreme desiccation. When conditions are dry, these ferns curl up and appear dead, but they can quickly revive and unfurl their fronds when moisture returns. Backpacking through mountainous Arizona wilderness I encountered small ferns growing in the shade of rock ledges, maybe this was Phillips Cliff Fern (Woodsia phillipsii). My guide called it “Ridgeline Fern” and claimed it was important for desert survival, could be eaten in extremis situations. This remarkable ability to withstand drought and promote human survival is a testament to the tenacity and usefulness of ferns.
Another intriguing aspect of ferns is their mutualistic relationship with mycorrhizal fungi. These fungi form symbiotic associations with fern roots, aiding in nutrient absorption and enhancing the fern’s ability to thrive in nutrient-poor soils. This partnership has likely contributed to the fern’s ability to colonize a wide range of habitats and compete with other plant species.
While ferns have proven to be resilient survivors, they have also played a crucial role in shaping Earth’s ecosystems. Ferns are often early colonizers in disturbed or newly formed habitats, and their presence can help stabilize soils and create conditions suitable for the establishment of other plant species. In this way, ferns contribute to the ecological succession and overall biodiversity of ecosystems.
Beyond their ecological significance, ferns have captured the human imagination for centuries. Their delicate and intricate fronds have inspired art, literature, and even garden design. Many garden enthusiasts cultivate ferns for their ornamental beauty and unique charm.
In conclusion, the eternal life of ferns is a testament to the remarkable adaptability and resilience of these ancient plants. Their longevity, dating back millions of years, serves as a reminder of the enduring nature of life on Earth. Ferns have evolved unique reproductive strategies, adaptations to various environments, and mutualistic relationships that have allowed them to persist and thrive. Whether they are serving as pioneers in newly formed habitats or gracing our gardens with their elegance, ferns continue to capture our fascination and enrich the natural world. Their legacy reminds us of the intricate and interconnected web of life that has persisted on our planet through the ages.

Juniper Sunrise
crack of dawn
In this post we start the day of my posting “Family Trek“, July 19, 2008, when, well before the sun rose at 6:23 am Mountain Daylight Time (the Navajo Reservation observes daylight savings, the rest of Arizona does not), Pam and I were at the Spider Rock Overlook.
Most visitors to the canyon make use of a system of roads and parking lots next to strategic views. There is the White House Overlook we visited our first day, July 18, to hike from the trailhead into the canyon. There are also, on the south side of the canyon:
- Tsegi Overlook, taken from a Navajo word that translates directly to “between the rocks” and usually refers to a deep canyon with steep cliffs.
- Junction Overlook above the point where Canyon Del Muerto (see my posting “Sun and Shade, Canyon Del Muerto”, and Canyon De Chelly intersect. There is an Anasazi ruin in the south-facing cliff across the canyon.
- Sliding House Overlook, another Anasazi run across the canyon.
- Face Rock Overlook, to view the eponymous formation.
- Spider Rock Overlook, the most stunning rock formation.

While getting ready I scoped out the location for interesting visual tropes. Utah Junipers are exceptionally hardy shrubs, stressed individual plants grow into compelling forms shaped by hardship. As the sun rose, this specimen emerged from the gloom and caught the first sun rays.

The Flatiron
Where is the ironing board?
The setting sun’s glow on the end point of Upper Siphon Draw trail, The Flatiron.
Click Me for my Online Gallery
The mountain was formed by a series of volcanic eruptions between 20.5 and 18 million years ago. The west face of the mountain is composed of dacite lava and rhyolitic tuff. The overlying tuff was deposited during an eruption which created a collapse caldera bounded by faults. Dome resurgence reactivated these faults, causing uplift of the caldera floor which juxtaposed the softer tuff and more resistant dacite. Differential weathering caused the outer tuff to erode faster, leaving the dacite cliffs exposed and creating the prominent mountain visible today.
The Flatiron, the mesa-like projection above us in this view, is long solidified dacite lava. The word dacite comes from Dacia, a province of the Roman Empire which lay between the Danube River and Carpathian Mountains (now modern Romania and Moldova) where the rock was first described.

Oak Creek Mandala
early one still morning
This quiet nook is hidden along the Oak Creek Canyon trail, though easy enough to find.
I visited there just at dawn when the air was still and the usually busy site deserted.
Oak Creek Canyon is named for the native, evergreen oak species unique to desert environments. The leaves conserve moisture: small, thick. I remember camping at the Chiricahua National Monument on November. All night the acorns fell onto the metal picnic tables, a loud metallic thunk.
The post header is a primrose flower growing on the bank of Oak Creek.
Recognize the rock from “Oak Creek Mandala”? This is farther up the Oak Creek Canyon trail, “photograph by Pam Wills.” I am in my warm weather photography kit of the time having passed the camera to Pam for the shot.
