lookout tree
A lookout tree is a simple fire lookout created by attaching a ladder or a series of spikes to a tall straight tree with a view of the surrounding lands, allowing rangers or fire crews to conveniently climb the tree to survey their surroundings. The simplest kind consist only of a ladder to a suitable height: this kind was called a "ladder tree." Some ladder trees had platforms on the ground next to them for maps and a fire finder. A more elaborate version often created a platform on top of the tree trunk by cutting off approximately the last of the treetop and building a railed wooden platform on the resulting stump. These "platform trees" were often equipped with telephones, fire finder tables, seats and guy wires. Accommodation for the watcher was provided by a tent or shelter at the bottom of the tree.
Lookout trees were widely used in the Kaibab National Forest of northern Arizona,〔(【引用サイトリンク】url=http://www.fs.usda.gov/recarea/kaibab/recarea/?recid=11695 )〕 and Washington, USA as well as in Australia. The Dave Evans Bicentennial Tree in Western Australia reaches 75m, while the tallest lookout in the United States was the Cook Creek Spar Tree near Lake Quinault, Washington, USA, at high from 1927 to 1955.〔(【引用サイトリンク】url=http://www.firelookout.org/towers/mn/mn-tower-brochure.pdf )〕
==Australia==
Eight karri trees were adapted as lookout trees in Western Australia in the 1930s and 1940s. The Gloucester Tree features a cabin in its top and may be climbed by visitors, as can the even taller Dave Evans Bicentennial Tree. The Diamond Tree continues in occasional use as a fire lookout.〔(【引用サイトリンク】url=http://www.pembertonvisitor.com.au/pages/pembertons-climbing-trees/ )〕
