Our weather was beautiful: sunny, cool, and breezy. I started out with a windbreaker but took it off within the first two miles.
Rather chilly winds at the start of the walk. |
Even Bob had long sleeves, but that was to protect himself from the sun. |
A beautiful vista of desert and snow-covered mountains. |
Cactus wren surveys all from atop a saguaro. |

Saguaro cacti have a lot in common with trees. For example, seedlings grow best when sheltered by "nurse trees." In a coniferous forest, tiny plants and trees can be found growing on "nurse logs." Saguaros in some places grow together so densely, they're called cactus forests. Birds make homes in saguaros just as birds make homes in other types of trees.
From the national park brochure:
"Saguaros grow very slowly at first--an inch or so during their first six to eight years. It may be 70 years before they sprout branches or arms. They reach full height, 40-50 feet, at about age 150. The tallest may reach 75 feet. Long, woody ribs support their multi-ton bulk.
"Saguaros collect water through shallow roots extending about as far outward as the main trunk is tall. As saguaros soak up water, accordion-like pleats in the trunk and arms expand to allow for storage in the spongy flesh. Waxy skin reduces moisture loss. Spines shade the plant, shield it from drying winds, and discourage damage from animals.
"Cream-colored flowers appear in early summer. White-winged doves, lesser long-nosed bats, honeybees, and moths feed on nectar and pollinate as they go. In July the deep-red fruit ripens, food for animals and humans. Doves, bats, javelina, and fox are among the animals that eat the fruit, while pack rats and jackrabbits eat the flesh of the cactus.
"Birds find not just food in saguaros, but homes as well. Gila woodpeckers and gilded flickers make nest holes in the trunks and large limbs. Others occupy abandoned holes or build nests in upper branches. Raptors perch on the tallest branches to spot prey."We did not spot any wildlife today, except a few types of birds and some butterflies. Horses are allowed into the park and the trails show it, many of which had deep ruts from horses' hooves.
Cholla or "jumping" cactus. |
A few small wildflowers are blooming. |
Well-marked trails, but you need to know how to read them. We're headed to the Mica View Trail. |
Mostly little wildflowers in bloom at this time. |
These are some very old saguaros. See Bob? He's 6' tall. |
Yellow evening primrose. |
Bob is by one of the stream crossings. |
Crystal-clear, long-distance views. |
Ocotillo cacti's red blooms are just starting at the tips of the stalks. |

Apparently a national park burro. |
After watching the slide presentation and looking around the small museum, we decided to do the Cactus Forest Loop Drive. The terrain was very hilly. Bob and I thought the scenery was pretty much the same as on our 10k walk earlier, only the walk was more up close and personal. We did the Desert Ecology Walk (only 1/4 mile) which was pretty lame after all that we had seen earlier.
Gotta love those views! |

Tile mosaic (?) of the Sonoran Desert. |
Gambel's quail and coatimundi. |
Mountain lion and red-tailed hawk. |
Western Collared Lizard and Cactus Wren. |
Identification key to flora and fauna. |
Tomorrow, we will do a 10k Volksmarch in Sabino Canyon AND an 11k Volksmarch in downtown Tucson. Until then, Travel Bug out.
