Technological change has interested archaeologists since the inception of the field, but persistence – particularly in a broader context of social transformation – is also a phenomenon that demands explanation. This paper examines the persistence of Indigenous silver production in Porco, Bolivia from Inka times to the twenty-first century, arguing that rather than solely being the result of either passive traditionalism or active identity creation, it can be most fully understood in terms of the intersection of technological practice with a changing local political economy.

Holocene climate in the high tropical Andes was characterized by both gradual and abrupt changes, which disrupted the hydrological cycle and impacted landscapes and societies. High-resolution paleoenvironmental records are essential to contextualize archaeological data and to evaluate the sociopolitical response of ancient societies to environmental variability. Middle-to-Late Holocene water levels in Lake Titicaca were reevaluated through a transfer function model based on measurements of organic carbon stable isotopes, combined with high-resolution profiles of other geochemical variables and paleoshoreline indicators. Our reconstruction indicates that following a prolonged low stand during the Middle Holocene (4000 to 2400 BCE), lake level rose rapidly ~15 m by 1800 BCE, and then increased another 3 to 6 m in a series of steps, attaining the highest values after ~1600 CE. The largest lake-level increases coincided with major sociopolitical changes reported by archaeologists. In particular, at the end of the Formative Period (500 CE), a major lake-level rise inundated large shoreline areas and forced populations to migrate to higher elevation, likely contributing to the emergence of the Tiwanaku culture.

As archaeologists we experience past time in the present, challenging linear time as we deal with the remains of different moments, events and people. This multi-scalar approach to time stimulates a flexible discussion of the past, understanding it not only in the absolute way provided by calendric dates, but also enmeshed within events and anchored by layers that were lived thousands of years ago. In this article, we will explore the notions of time of the people living in a densely populated settlement in the coastal Andes (AD 550–850), by focusing on the seasonality of quotidian practices, on cyclic constructive events and on the recurrent interment of people within residences.
