Mail Creek, Arizona -- Could you guess?

This is Mail Creek, just below the Mogollon Rim, before it joins the upper East Verde River near Washington Park, Gila County, Arizona. At this point the creek is just about 6000 feet above sea level and is part of the Central Highlands. The Rim, behind all the trees to the north, is the edge of the Colorado Plateau and the rocks in the picture are a mixture of granite and rhyolite with the sandstone and limestone of the plateau. Quoting from Arizona Roadside Geology from Northern Arizona University:

Unlike the Colorado Plateau to the north, igneous and metamorphic rocks are well exposed in many areas in this region. In several areas granitic plutons have intruded into overlying sedimentary rocks. The heat and water associated with this magma caused intense mineralization of nearby rocks, particularly limestone, and copper minerals formed. These valuable copper deposits have been mined historically and are being mined today in the Clifton-Morenci area and the Globe-Miami area. The mines contain low-grade ore (not very concentrated) so huge open-pit mines have been dug to extract enough rock to gather the copper.

Interestingly, some quartzite pebbles associated with ranges south and below the Mogollon Rim have been found in stream deposits atop the rim and to the north. How did they get there? It appears that at one time at least one of the ranges of the Central Highlands, the Mazatzal, was once above and connected to the Colorado Plateau. The Mogollon Rim did not yet exist, and sediment from this range was shed northward onto the plateau.

This area is also known as the Apache Highlands Ecoregion. The vegetation is know as the Western Xeric Evergreen Forest and is a mixture of conifers and deciduous trees.
