Oregon Trees Create a Smiling Face on the Mountain

A remarkable forestry intervention in Oregon alters the mountain landscape with every seasonal change. This imaginative project uses different tree species to create an enormous smiling face, visible from a distance along the motorway.

How can a forest in Oregon smile during autumn?

In Polk County, a distinctive project conceived by Hampton Lumber helped restore the local area. Skilled foresters worked out the precise placement of every sapling to create a striking reforestation design on the verdant hillside in the county.

Measuring roughly 91 metres across, the vast image catches the eye of drivers on the motorway. The effect is created because the selected plants respond differently to cooler weather, producing a pronounced contrast in leaves during autumn.

Which tree species were used in this unusual project?

Forestry specialists selected larch trees to form the eyes and the smile. As an uncommon deciduous conifer, this species sheds its yellow needles before winter, bringing out the features of the figure across the ground.

Thousands of Douglas firs were planted around the central design to provide the image’s dark backdrop. These trees remain green throughout the year, ensuring the smiling face on the mountain stays clearly defined.

Below is a video from The Oregonian (Open Oregon) YouTube channel that explores the points discussed in this topic in greater depth:

Why does the colour change happen only at a particular time?

Throughout spring and summer, both plants display very similar green tones within the dense forest. This natural similarity conceals the design from view until temperatures begin to fall as the temperate climate arrives in the region.

As daylight hours shorten, the larch stops producing chlorophyll and turns a vivid golden colour. This biological cycle produces a dynamic visual display that lasts only a few weeks before the yellow needles fall from the canopies.

Elements of the Smiling Landscape

Design components
Discover the essential factors behind creating this figure on the mountain:

1. Yellow larches planted for autumn;
2. A permanent base formed by green Douglas firs;
3. Precise geodetic positioning carried out by foresters.

How did forestry planning shape this remarkable work?

Creating the design required exact calculations throughout the planting process undertaken by the field teams. Every tree was placed strategically so its canopy would grow to the correct proportion, preserving the perfect geometry of the smile for decades.

Projects of this kind show how modern forestry can bring sustainable management together with urban art. The initiative turned an ordinary commercial site into a visitor attraction admired by travellers crossing the valley on their journeys.

The principal environmental elements that keep this image alive through the seasons are listed below:

• Biological combination: choosing plants with differing leaf behaviour throughout the year;
• Ongoing management: maintaining the pattern during normal timber-harvesting operations;
• Geodetic positioning: carefully aligning saplings during the initial reforestation stage.

How long will this giant face remain visible on the hillside?

Experts estimate that the image will continue to emerge every autumn for several decades, until the final harvest takes place. The species used have a long growth cycle, ensuring this natural work remains on the region’s horizon.

As time passes, the trees become stronger while keeping the smile visible for future generations of residents. This creative legacy left by the workers shows how small actions can bring surprise and joy to the watching public.
