In 1925, the Snoqualmie Falls Lumber Company planted one sycamore tree in front of each mill house in what was known in the Riverside Neighborhood in the mill town of Snoqualmie Falls.  All the houses were moved to other places in the Valley in the 1950s, leaving the trees that now form a vegetative tunnel along the road.

The last remaining remnants of the historic town of Snoqualmie Falls.
