David Hampton planted douglas fir and larch trees in a forest in Oregon to resemble a face. Every autumn the larch pines turn orange and the smiley face stands out
The face is about 300 feet in diameter.
rope was used to measure the circle douglas fir was planted for the eyes and mouth and the rest of the face was filled out with larch. both species will eventually be harvested but will smile at least for the next 30-50 years
