The Fremont’s Cottonwood (Populus fremontii) is a poplar tree native to the American Southwest and south through central Mexico.  The tree was named after John C. Fremont, the 19th century American explorer.  The riparian tree grows near streams, rivers, springs and wetlands below 6,600 ft elevation.  This scene of a Fremont Cottonwood was photographed along the Aqua Fria River in the Agua Fria National Monument near Cordes Lake, Arizona, USA.

The Gambel Oak (Quercus Gambelii) is a deciduous tree that commonly grows among the sagebrush, east of the Cascade Mountain Range, in the Pacific Northwest. During the spring and summer, the oaks use sunlight and chlorophyll to create food necessary for the tree’s growth.  In late summer and early fall, the Gambel oak produces acorns which are a source of food for many animals. Later in the fall, as the days get shorter and colder, the naturally green chlorophyll in the leaves breaks down and they stop producing food.  Other pigments are now visible, causing the leaves to take on beautiful orange and gold colors.  These colors can vary from year to year depending on weather conditions.  For instance, when autumn is warm and rainy, the leaves are less colorful.  This lone oak tree on a hillside was photographed in Naches along the Yakima River near Yakima, Washington State, USA.
