A small book describing the process of construction of a tree-ring chronology from scratch till it becomes several-millennia long. chronology, using species growing in aride climates, for which ring width series matching differs substantialy from that for oak. If the rings don't correlate, how can they be used for archaeology?

There are plenty of tree-ring-width graphics comparing two or, usually, more anual tree-ring-width series; describing too how sutiable timbers are seeked for and eventually found (or not), the unexpected outcomes in terms of history of Irish oak forests and other surprises arising from dating of archeological timbers, the two-pass correlation with Germany via England, and more. It is a pity it doesn't include the final linking of the several prehistoric floating chronologies, they were not yet complete at the time of writing. I decided to to a study of tree rings when I read how they supposedly matched up the tree rings from some 8000 year old tree to some dead older tree to extend the timeline to 12,000 years.

It is the science of assigning calendar-year dates to the growth rings of trees, and Colorado figures prominently in its development and application in archaeology and other disciplines.

Tree-ring dating provides scientists with three types of information: temporal, environmental, and behavioral.

Most chronologies only go back a few centuries, but a few give longer ages than the Bible seems to allow, supposedly up to 10,000 years or so. Year-to-year variation in the width of rings records information about the growth conditions in the particular year.

Insect infestation clearly manifests itself, as does disease or fire damage. Day length, amount of sunshine, water potential, nutrients, age of tree, temperature, rainfall, height above ground, and proximity to a branch all impact tree growth and tree ring production.

The temporal aspect of tree-ring dating has the longest history and is the most commonly known—tree rings can be used to date archaeological sites, such as the Cliff Dwellings found at Mesa Verde National Park (MVNP) or historic cabins.

The environmental aspect of tree-ring dating today has the most worldwide application, as tree rings can be used to construct records of ancient temperature, precipitation, and forest fire frequency.

Archaeologists sometimes study the ring patterns in beams or other pieces of wood from archaeological sites to help date the sites; they may also study the ring patterns to infer the local climatic history.

While the premium matchmaking service use algorithms to create a pool of matches, it prides itself on then handpicking your perfect partner.

By winter, when the sap finally stops flowing, a smooth dark ring marks the end of the tree’s annual growth.

By counting the dark ring segments, scientists can tell a tree’s age if the cross section of the trunk is complete. Based at the University of Arizona in Tucson, Douglass wanted to know how sun spot activity affected climate, and his research soon led him to pioneering tree-ring analysis.

As the summer winds down and the transition to the cooler autumn occurs, the tree’s growth rate slows.
