history

We walk on layers of history. In our neighborhoods, in our cities, there were once natural phenomena, like creeks, sand dunes, hills, and forests. Over time they were covered in farms, factories, houses, and most of all, streets. At first those streets were dirt, often thick and muddy. Around the middle of the 19th century they started to be used for railroads, both intercity, and local streetcar and cable car lines. Sometimes the shape of our 21st century streetscape is a ghost of those old train lines.
