Afton's most photographed landmark is an archway spanning Washington Street, built from thousands of interlocking elk antlers. The original arch was constructed in 1958 using antlers collected from the surrounding hills and valleys, and it has been rebuilt and expanded over the years. It stretches roughly 18 metres across and 6 metres high, containing over 3,000 antlers. Elk shed their antlers naturally each year, so the supply is renewable, though the scale of the collection is remarkable.
The arch stands at the centre of Afton's main commercial strip and is visible from a distance as you drive into town. Worth a stop and a photo; the scale is surprising. There is a small visitor information kiosk nearby in summer.
