Gambel oak

Quercus gambelii, the Gambel oak, is a deciduous small tree or large shrub widespread in the foothills and lower mountain elevations of the central southwestern United States and northwestern Mexico: its range is centered on the Colorado Plateau–Four Corners states of Utah-Colorado, Arizona-New Mexico, but ranges into Nevada, Wyoming, South Dakota, Kansas, Oklahoma, and west Texas. In Mexico mostly north Sonora-Chihuahua. It typically grows at altitudes of 1,000–3,000 meters above sea level, where precipitation averages between 30–60 centimeters (12 to 24 inches) per year. It is often called scrub oak, oak brush or white oak.
