After this occurs and once the tubes are securely in place, a hookah compressor and a low-pressure hose re-inflates them so that they form a tight grip around the floating logs. This process gives the logs more buoyancy and gives loggers easier access points to harvest them. As many tubes that are needed are used to float the logs. [4]
Floating logs down a river worked well for the most desirable pine timber, because it floated well. But hardwoods were more dense, and weren't buoyant enough to be easily driven, and some pines weren't near drivable streams. Log driving became increasingly unnecessary with the development of railroads and the use of trucks on logging roads ...
A splash dam was a temporary wooden dam used to raise the water level in streams to float logs downstream to sawmills. [1] By impounding water and allowing it to be released on the log drive's schedule, these dams allowed many more logs to be brought to market than the natural flow of the stream allowed.
A "full deck" of logs awaiting the mill. 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.
Whale watchers in San Diego were in for quite a treat recently when a pod of bottlenose dolphins stole the show by leaping 20 feet out of the water to the delight of everyone on board.
In the early days, felled logs were transported using simple methods such as rivers to float tree trunks downstream to sawmills or paper mills. This practice, known as log driving or timber rafting, was the cheapest and most common. Some logs, due to high resin content, would sink and were known as deadheads.
Log boom on St. Croix River in Maine, aerial photo taken in 1973 Timber marks on a log building in Sweden where they are called flottningsmärke. A log boom (sometimes called a log fence or log bag) is a barrier placed in a river, designed to collect and or contain floating logs timbered from nearby forests. The term is also used as a place ...
A boom is "a barrier composed of a chain of floating logs enclosing other free-floating logs, typically used to catch floating debris or to obstruct passage". [3] The Susquehanna Boom extended seven miles (11 km) upstream [ 4 ] from Duboistown to the village of Linden in Woodward Township where it was interrupted to create a channel across the ...
