Strata

After a recent illuminating lecture by Shannon Mattern (here's her blog: Words in Space), I have added to my visual attuning catalog the exposures of urban layering, in particular where media structures have been erected, poured, or otherwise placed atop older media structures running the same routes.
Bicycling home from work at Luther, I have tried to take slightly different routes to map the city bit by bit daily. I saw this piece of road work underway and was surprised that the brickwork cobblestone street remained underneath the layers of paving. Stop to look closely, and you can see the texture struck into the bricks of horseshoes and wagon wheels.
