It has only 178 inhabitants and one post office. Index was first settled by the Skykomish Indians who made a living fishing in the Skykomish River. In the late 19th century, gold was discovered at nearby Monte Cristo, WA and many prospectors and settlers came to the area from other parts of the U.S. Index is situated in the Western foothills of the Cascade Mountains and the town of index is named after nearby Mount Index that lies just three miles south of town. The community of Index is surrounded by huge Granite cliffs that reach 500-feet high on the north side. These granite cliffs make Index a major international destination for rock climbers because the cliffs manifest a type of high-quality cracks that are ideal for this sport. Hiking, swimming, white-water rafting, or simply enjoying spectacular natural scenery are other reasons why Index is an important tourist destination.
