Boulder Map Art

Boulder's grid runs north-south along Pearl Street, hemmed in tightly by the Flatirons ridge to the west and the Boulder Valley spreading eastward. Streams from the mountains—Boulder Creek, Bear Creek, South Boulder Creek—cut diagonal paths through the street pattern, creating green corridors that interrupt the blocks. The city's edge stops abruptly where development meets the open space buffer, a sharp boundary visible on any map.
