This paper looks at change over time in the landscape and material culture of Silicon Valley, California. It returns to research first presented to CAA at Ljubliana in early 2000, when the area was still regarded as the epicenter of the dotcom boom. The author explored the material culture - the artefacts - of Silicon Valley through the eyes of an archaeologist, noting the rate of change over a turbulent 12 months of the year 2000, and presenting Silicon Valley as evidence gathered in an assemblage which ranged from homes and commercial buildings, to lifestyle choices and personal technology. Re-evaluating the data in 2003, the rapid changes precipitated by the economic downturn can be considered in the same way as the 'goldrush' days of the dot.com boom. What is left for field study now, and how valid is this archaeological analogy?
