Core sample from living tree
I don’t have to cut down trees to read their rings. Using a special tool called an increment borer, I can take a core sample from a living tree. A core cample is about the size of a soda straw, and the rings look like lines. I found an old log cabin while hiking last week. I took a core sample from the logs to find the age of the cabin.

Use the core samples to complete the chart below. Compare the core samples to see where the patterns of the rings match. The last ring of the living tree grew in the year 2024. Count backwards from the bark to find out the age of each tree. Cutting out the strips makes comparing easier.
