used to date certain kinds of trees, but only in some parts ofthe world
Tree-ring dating has been mostsuccessful in the Southwestern U.S. and in Europe, although tree-ring chronologies arebeing developed for other areas. In the Southwest U.S., dendrochronology can be usedback to around 300 BC. Advantages: This is the most accurate dating method, since itcan allow dating to the year or even the season the tree died. It also allows us toreconstruct past climates. Disadvantages: It works only in limited areas of the world, andonly on certain species of trees. In the Southwest, it can be used mainly on the ColoradoPlateau and in the mountains (on pines, firs, or spruces), but not in the deserts (mesquite,palo verde, ironwood, etc. cannot be dated).
