1989 Map of Index

About this map

Index sits at the dramatic confluence of river and ridge, serving as the central hub of this Snoqualmie National Forest landscape. The topography is dominated by the Skykomish River, which divides into the North Fork and South Fork. The mapping details a series of powerful water features that shaped the local geography and economy, from the tiered cascades of Bridal Veil Falls and Sunset Falls to the high-elevation waters of Lake Isabel and Lake Serene.
