Sign Post Forest, Territorial historic roadside attraction in Watson Lake, Canada.

Sign Post Forest is a collection of over 80,000 directional signs, license plates, and markers from worldwide locations spread across several hectares. The signs are mounted at varying heights and angles, creating a dense array of text and metal.

In 1942, Private Carl K. Lindley of the 341st Engineers began this collection by posting a sign pointing to his hometown of Danville, Illinois. What started as a single personal gesture grew over the decades into an internationally recognized site.

Travelers from around the world leave their marks by adding signs, license plates, and personal markers representing their hometowns and countries. This ongoing collection reflects the personal connections people feel to the wider world.

The collection sits at the junction of the Alaska Highway (Route 1) and the Robert Campbell Highway (Route 4) in central Watson Lake, taking up a couple of acres among the trees. Visitors may add their own sign to the more than 100,000 already there. The posts stand on gravel, and new panels are added continually, so the layout shifts over time.

The forest began with a single repaired signpost: in 1942 a bulldozer damaged the distance marker on the tote road, and Private Carl K. Lindley of the 341st Engineers was ordered to fix it. He added "Danville, Ill. 2835 miles" pointing home, and others copied him. In June 2012 the stage in the centre hosted an impromptu performance of "Two Women on a Precipice" for travellers stranded by mudslides.
