The tree on the left is our “big tree”. (Click the image to see the full height.) It’s the largest diameter and tallest tree on our property. After measuring some nearby trees of similar height using the NASA Globe Observer app, I now think that the big tree (which is about 7 feet in diameter) is more than 250 feet tall.
(The tree to the right is considerably smaller. It sits a bit higher and it’s only about 4 foot diameter but like most redwoods, it grew tall before wide.)
