1989 Map of Index

About this map

Index serves as the central hub of this mountain landscape, positioned at the confluence of the North Fork and the South Fork of the Skykomish River. The late 1980s topography reveals a geography defined by extreme vertical relief, featuring peaks like Mt Index and Mt Persis that dwarf the river valleys below. Evidence of earlier industrial infrastructure is present in the Old Railroad grade and nearby Fish Ponds, while more contemporary developments include a Trailer Park and a Radio Facility tucked into the lower elevations. The map is particularly notable for its high concentration of cascades, documenting Bridal Veil Falls, Eagle Falls, Sunset Falls, and Canyon Falls. Alpine lakes such as Lake Isabel, Lake Serene, and Lost Lake dot the high reaches of the Snoqualmie National Forest, illustrating the transition from river-bottom commerce to protected wilderness.
