  In the late nineteenth century, it would have been a brave undertaking for a woman to tromp around the wilds of the Colorado Plateau. But that is what Alice Eastwood did, in long skirt and fine flowered hat, following her passion for plants.

Born in Canada in 1859, Eastwood grew up in Denver and was a high school teacher there for a time. Armed with field guides and a plant press, she spent vacations exploring all over the West. An energetic woman, she traveled by foot, horse, and rail, and eventually won welcome to an all-male hiking club.

  They’re an animal many gardeners love to hate, though they’re rarely seen. Ribbons of dirt strung across the ground, and sometimes disappearing plants, are the only sign most people will see of pocket gophers, rodents that themselves are very active gardeners.

The dirt trails are created as these small animals excavate underground tunnels where they live, store food, and bear young.

 Archaeologists have long appreciated that the Southwest’s dry climate is ideal for preserving perishable goods left by past people. Cloth, basketry, wood, or plant and animal materials that have survived for nearly a thousand years are rare, exciting finds.

Such a discovery was made on a ranch near Montezuma Castle in central Arizona, and the entire collection was recently donated to the Verde Valley Archaeology Center in Camp Verde.

  The Colorado pinyon pine, the tree that covers millions of acres of the Colorado Plateau, bears hard-shelled, wingless seeds in stubby cones. And people in the Southwest have harvested and eaten those delicious nuts for thousands of years. 

But the pines produce nuts only every five to seven years. When there was a good crop in the fall, whole families trekked to the woodlands to gather the protein- and calorie-rich nuts, which nourished them through the winter.

The American beaver is an appealing animal, with dexterous paws, curious eyes and paddle-shaped tail. But, these rodents, the largest in North America, were nearly wiped out by the early 1900s as trappers sent mass quantities of the thick brown pelts back East for stylish top hats.

The Colorado Plateau has seen its share of energy booms and busts. In eastern Utah, another one may be poised to begin.

On Sept. 3, 1964, President Lyndon Johnson signed the National Wilderness Preservation System Act. With the stroke of a pen, 9 million acres of federal land in the United States was designated as wilderness — with a capital “W.”

In the 19th century, William Henry Jackson introduced many Americans to the scenic wonders of the country’s West — and to the power of landscape photography.

On the Colorado Plateau, life begins anew when the monsoon rains come — especially for native amphibians like the northern leopard frog. This beautiful, spotted, greenish-brown frog pays close attention to moisture, and starts to move on humid days and rainy nights.

Can a plant that grows in only three national forests in Arizona survive all that today’s changing environment can throw at it?
