NPS Sitka National Historical Park

Location: Sitka, Alaska

Sitka National Historic Park is home to 25 stately totem poles which stand as powerful symbols of the past. In 2009, faced with 120,000 annual park visitors, and limited staff, the park saw an opportunity to augment their ranger-led totem tours with technology. Five years later, more than 12,000 visitors have toured the park's totem poles from their phones. Sitka uses their mobile app to provide audio interpretation with transcriptions for each stop.
