Logs with a higher density than the density of water would sink. [2] Other logs would get caught in jams, sloughs, or floods, and become lodged in the riverbed. Such logs were often known as "sinkers" or "deadheads." Loggers attempted to reduce the number of logs which remained in the river in order to maximize profits, but some losses were ...
The formation of a log jam against one bank typically concentrates flow in the wood-free portion of the channel, increasing velocity through this section and promoting scour of the riverbed. The formation of channel-spanning log jams can lead to the formation of an upstream pool, water spilling over the structure generating a "plunge pool ...
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.
One of the largest issues with treatment on waterlogged wood is finding a way to remove the water in the wood but keep the water that is part of the material. Preventing cell wall collapse (which causes shrinking, cracking, and further damage) of the waterlogged wood while drying is the largest struggle and main goal of treatment.
The person bucking is generally called a bucksawyer or bucklogger, or just a bucker and runs as many saws as he can, switching saws as soon as one is dull. The reason for this is the bucksawyer is typically paid per section of log he cuts. Generally buckloggers at smaller sawmills are not fully mechanized. This part of the logging process is ...

There the logs were decked onto "rollways." In spring when snow thawed and water levels rose, the logs were rolled into the river, and the drive commenced. [6] To ensure that logs drifted freely along the river, men called "log drivers" or "river pigs" were needed to guide the logs. The drivers typically divided into two groups.
Log splitting is the act of splitting firewood from logs that have been pre-cut into sections (rounds, bolts, billets [3]). This can be done by hand, using an axe or maul, or by using a mechanical log splitter. [4] When splitting a log by hand, it is best to aim for the cracks (called checks), if there are any visible. [5]
