A green chain is a type of lumber delivery system that can be used in a sawmill. The green chain's purpose is to collect the final product of the mill and move it at a controlled rate to be graded and sorted. [1] In the 19th and early to late 20th century, the green chain was used by people. Men would stand alongside and pull lumber that matches the required dimensions and place it in piles. In short, the workers sorted the lumber. Modern sawmills use automatic systems, such as the lumber dropping through the chain into large slings, where it can be picked up and moved to a staging area to dry. Most likely called the green chain because the lumber is green and has not been seasoned.

Lumber wood that has been processed into beams and planks

Lumber or timber is a type of wood that has been processed into beams and planks, a stage in the process of wood production. Lumber is mainly used for structural purposes but has many other uses as well.

Sawmill facility where logs are cut into timber

A sawmill or lumber mill is a facility where logs are cut into lumber. Modern saw mills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes. The "portable" saw mill is iconic and of simple operation—the logs lay 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 saw mill consists of a chainsaw and a customized jig, with similar horizontal operation.

Logging the cutting, skidding, on-site processing, and loading of trees or logs onto transport vehicles

Logging is the cutting, skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Logging is the process of cutting trees, processing them, and moving them to a location for transport. It is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions.

Portable sawmills are sawmills small enough to be moved easily and set up in the field. They have existed for over 100 years but grew in popularity in the United States starting in the 1970s, when the 1973 oil crisis and the back-to-the-land movement had led to renewed interest in small woodlots and in self-sufficiency. Their popularity has grown exponentially since 1982, when the portable bandsaw mill was first commercialized.

St. Croix Boom Site United States historic place

The St. Croix Boom Site is a historic and scenic wayside on the St. Croix River in Stillwater Township, Minnesota, United States. It commemorates the location of a critical log boom where, from 1856 to 1914, timber from upriver was sorted and stored before being dispatched to sawmills downstream. The site was developed as a roadside park along Minnesota State Highway 95 in the 1930s. In 1966 it was designated a National Historic Landmark for its national significance in the theme of industry. It was nominated for being the earliest, most important, and longest serving of the log storage and handling operations that supported Minnesota's major logging industry. Virtually no traces remain of the site's original buildings and structures.

The Susquehanna Boom was a system of cribs and chained logs in the West Branch Susquehanna River, designed to catch and hold floating timber until it could be processed at one of the nearly 60 sawmills along the river between Lycoming and Loyalsock Creeks in Lycoming County, Pennsylvania in the United States. The Susquehanna Boom was originally built under the supervision of James H. Perkins, and operated from 1851 to 1909, when it shut down for lack of timber.

Pennsylvania Lumber Museum

The Pennsylvania Lumber Museum is near Galeton, Potter County, Pennsylvania in the United States. It documents the history and technology of the lumber industry that was a vital part of the economic development and ecological destruction of Pennsylvania.

Reclaimed lumber

Reclaimed lumber is processed wood retrieved from its original application for purposes of subsequent use. Most reclaimed lumber comes from timbers and decking rescued from old barns, factories and warehouses, although some companies use wood from less traditional structures such as boxcars, coal mines and wine barrels. Reclaimed or antique lumber is used primarily for decoration and home building, for example for siding, architectural details, cabinetry, furniture and flooring.

Nagrom was a town in King County, Washington, United States. A logging company town, Nagrom was located in the Green River watershed between Kanaskat and Lester. The town was built by the Morgan Lumber Company and named after Elmer G. Morgan, the company founder and owner. The site was chosen for its access to timber and suitability to build a sawmill and mill pond. In 1910, Morgan petitioned the Northern Pacific Railway, which operated the rail line out of Puget Sound and up over Stampede Pass, to build a spur into the small town. The railway balked, but Morgan persisted and eventually the railway relented. The spur into town was built in 1911. A post office was established that same year, along with a telephone and telegraph exchange.

The Finkbine-Guild Lumber Company was established to harvest and market the virgin longleaf pine stands of southern Mississippi during the early 20th century. The main sawmills were located in Wiggins and D'Lo, Mississippi. When the local timber supply dwindled, the company tried to utilize redwood trees from California, but that operation failed because of high transportation costs. Other attempts were made at promoting a more diversified use of the cutover timberlands; some ventures were successful while others were not.

Usal Creek river in the United States of America

Usal Creek is the southernmost drainage basin unbridged by California State Route 1 on California's Lost Coast. The unpaved county road following the westernmost ridge line south from the King Range crosses Usal Creek near the Pacific coast, but the bridge may be removed during winter months. Usal Creek, 9.7 miles (15.6 km) long, drains about 28 square miles (73 km2) on the Mendocino Coast and empties into the Pacific Ocean near the former company town of Usal.

Lumber and wood products are created in the wood industry from the trunks and branches of trees through a series of steps, as follows.

Log pond

A log pond is a small natural lake or reservoir used for storage of wooden logs in readiness for milling at a sawmill. Although some mill ponds served this purpose for water powered sawmills, steam-powered sawmills used log ponds for transportation of logs near the mill; and did not require the elevation drop of watermill reservoirs.

The wood industry or lumber industry is a—usually private—economic sector concerned with forestry, logging, timber trade, and the production of forest products, timber/lumber, primary forest and wood products and secondary products like wood pulp for the pulp and paper industry. Some largest producers are also among the biggest timberland owners.
