Map and Explore: Hidden Hydrology
Jason King,  Portland

Our cities are filled with hidden stories. Some of these tales are unlocked through conversations with long-time residents and oral histories, while others emerge through the written word, embedded in documents and biographies from the shapers and boosters that made our cities. Some hide in maps, a chronology of layers of changes over time, intimately spatial and tied to places,...

However, even on this congested pathway on any given day you are likely to see red-whiskered...
