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 ...
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.
The second type of hazard occurs as the ice jam breaks apart, and a sudden surge of water breaks through flooding areas downstream of the jam . Such a surge occurred on the St. Lawrence River in 1848. [14] The third hazard is that the ice buildup and final drive may damage structures in or near the river [15] and boats in the river.
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]
Here's why January's reputation for cold and snow is well deserved. ... Salt Lake City (12.7 inches) and St. Louis (5.7 inches), are some of the larger cities where January is the snowiest month ...
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.
The area has seen almost two feet of snow in the last day and the game-time forecast calls for below-freezing temperatures, winds around 10 mph, and snow flurries. Fans were warned to expect ...
Log jams form when trees floating in the water become entangled with other trees floating in the water or become snagged on rocks, large woody debris, or other objects anchored underwater. They can build up slowly over months or years, or they can happen instantaneously when large numbers of trees are swept into the water after natural disasters .
