were fashioned from driftwood frames covered in skins. The Inuit classified driftwood into seven different types, each possessing its own unique material and visual properties. Driftwood could be used to make bows if it was straight grained and in reasonably good condition; these were reinforced with sinew cables. The Inuit even made arrows from driftwood; these were often short and fitted with bone or antler foreshafts. Dry scrapings produced by working this material were collected, stored and used for the starting of fires year-round by Inuit. Wood that is burned today in these regions mainly consists of the remains of condemned wooden structures. Driftwood is still used as kindling by some. Woods with resinous qualities, such as cedar, are preferred for their lengthier burning times.

'' logs spent enough time exposed to wave action to round their contours before being driven into the mouth of a narrow ravine by storm surf. Sequoia's high tannin content is resistant to decay, so these logs retain structural strength for decades. Storm flows within Shorttail Gulch are insufficient to move the logs back to sea. This unique habitat at the mouths of small estuaries of the California coast is threatened by the diminished quantity of large redwood logs available in flood waters since the logging of native forests.
Decline
With the advent of industrial logging practices, the global quantity of driftwood has declined. Early accounts indicate that driftwood was once more plentiful. Early photographs of the Pacific coast reveal greater amounts of driftwood on the beaches than is present today. Likewise, when traveling in Dixon Entrance in the late 1800s, George A. Dorsey recorded that many beaches were "piled high with drift, often to a height of sixty feet or more." Melting polar ice may also contribute to the decline of Siberian driftwood in the Atlantic as the sea ice enabled driftwood to travel greater distances without becoming waterlogged.
