One of the coolest things we've seen all year is this interactive map from developers Dan Vanderkam and Raven Keller that places around 13,000 old images from the San Francisco Historical Photograph Collection onto their locations around the city. A slider tool allows users to travel back in time to the Financial District and SoMa circa 1853. Move forward in time and images start to pop up in more far-flung locations. We've compiled some of our favorites from 1850 through 1899 here. They range from a saloon perched out near Ocean Beach to an 1882 snowstorm in the heart of Union Square. All show a city in its very early days, when much of San Francisco looked more like a frontier town than the city it would eventually become.
