There is something so geological about Thiebaud's view of the city: buildings and roads are like shards of rock, as vertiginous as cliff faces. These are drawings where the x-axis has been multiplied by 10, the unbuilt landscape is mysterious — an enormous clamshell holding itself to itself, the road is both brave and intimate: a tremendously exciting place to live, as San Francisco is. Thiebaud introduces a powerful scale with which to identify one's place in this city way beyond the vocabulary of urbanism. The city is like a Krazy Kat mesa: a figure in the landscape that one lives up against.
