1989 Map of Index

About this map

The town of Index sits at the confluence of the north and south forks of the Skykomish River, serving as a focal point for the mountain landscape of the Snoqualmie National Forest in the late 1980s. The geography is defined by significant vertical relief, where peaks like Mt Index and Mt Persis tower over deep river valleys. The presence of an Old Railroad Grade and scattered sites labeled mine, quarry, and prospect reflect the region's historical reliance on extraction and transport.
