in case u were interested in just how big a Raft can be...
The Great Raft was a gigantic logjam or series of "rafts" that clogged the Red and Atchafalaya Rivers and was unique in North America. It has been speculated that the trees in the jams were knocked down by an impact event. It probably began forming around 1100–1200 AD.
The Great Raft grew faster at its upper end than the lower end decayed or washed out, leading to its peak length spanning more than 160 miles/250 km in the early 1830s. The raft, at one point, extended for 165 miles from Loggy Bayou to Carolina Bluffs.
Steamboat builder and river captain Henry Miller Shreve (1785–1851) began systematically removing the Great Raft, a task that was continued by others until the latter part of the 19th century. For his efforts the city of Shreveport, Louisiana, was named after him.
When Shreve began work the Raft was 8 miles directly below to 17 miles directly above Shreveport.
Captain Shreve had removed the raft up to the mouth of Twelvemile Bayou in April 1835. Shreve concluded this work in 1838, having removed the last impediment to navigation on the Red River.
