A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the motorized saw cuts the log horizontally along the length of the bed, by the operator manually pushing the saw. The most basic kind of sawmill consists of a chainsaw and a customized jig ("Alaskan sawmill"), with similar horizontal operation.

Before the invention of the sawmill, boards were made in various manual ways, either rived (split) and planed, hewn, or more often hand sawn by two men with a whipsaw, one above and another in a saw pit below. The earliest known mechanical mill is the Hierapolis sawmill, a Roman water-powered stone mill at Hierapolis, Asia Minor dating back to the 3rd century AD. Other water-powered mills followed and by the 11th century they were widespread in Spain and North Africa, the Middle East and Central Asia, and in the next few centuries, spread across Europe. The circular motion of the wheel was converted to a reciprocating motion at the saw blade. Generally, only the saw was powered, and the logs had to be loaded and moved by hand. An early improvement was the development of a movable carriage, also water powered, to move the log steadily through the saw blade.

Mingus Mountain (Yavapai: Hwa:lkyañaña) is a mountain located in the U.S. state of Arizona in the Black Hills mountain range. It is located within the Prescott National Forest traversed by State Route 89A approximately midway between Cottonwood and Prescott. The summit can be reached via Forest Service roads that branch off from State Route 89A. From the mountain, there are views of the Verde Valley, Sycamore Canyon Wilderness and the towns of Cottonwood, Jerome, and Clarkdale. The Woodchute Wilderness, north of the highest point of 89A, also offers views and hiking trails. There are several National Forest campgrounds in the area and it is the transmitter location for Prescott full-service television station KAZT-TV and several low-power television stations serving Cottonwood, Clarkdale, Camp Verde and Prescott Valley. Mingus Mountain is also the premier flying site of the Arizona Hang Gliding and Paragliding Association.

According to the book, Roadside History of Arizona, by Marshall Trimble, "Mingus Mountain was named for Joseph and Jacob Mingus, two brothers who settled in the area in the 1880s and later operated a sawmill near the base of the mountain". Another source attributes the name to William Mingus (d. 1911, Prescott, Arizona), a pioneer prospector who lived and worked on Mingus Mountain in the 1870s.
