The issue of whether we have now exited the Holocene epoch and entered a new geological interval defined by the actions of humanity-the Anthropocene-is currently the subject of significant scientific debate. Whereas some argue that humans are now the dominant force shaping the surface of the earth, and that the changes we are creating will be preserved in future geological strata (Crutzen 2002; Waters et al. 2016), others are dubious of the justification, practicality, or value of the Anthropocene in a world in which action, rather than definitions, are required (Scourse 2016). The ethical, philosophical, and moral dimensions of this debate, however, have taken it beyond the sciences, arguably inspiring a shift in the arts, humanities, and social sciences (Lorimer 2012; Yusoff 2013; Johnson et al. 2014; Buck 2015). Matless's (2016) proposition of the "Anthroposcenic" foregrounded "the way in which landscape becomes emblematic of environmental transformation" (118). His proposition focused on how places, sites, and landscapes such as eroding coastlines or melting glacial snouts became "scenes through which processes interrogated under Anthropocene and climate change rubrics become evident" (Matless 2016, 118) and so provided "a stepping point for Anthroposcenic stories" (Matless 2017, 2), and "meeting points with science" (Matless 2016, 118). In so doing, he extended and enriched the Anthropocene concept and offered a new opportunity to creatively explore places and landscapes influenced by human activity. This article records the responses of four writers to the landscapes of the upper River Ystwyth and Cwm Elan (Elan Valley) in the Cambrian Mountains, mid Wales. Our aims were to engage with the concept of the Anthropocene in a landscape that could be emblematic of the proposed new geological interval. Through poems and prose inspired by these landscapes, the physical, social, cultural, and political processes shaping them are explored. The pieces have a strong sense of place, and touch on themes of pollution of the environment by heavy metals, geomorphological impacts of dams, and the human stories associated with those places. These pieces were written especially for performance at the "Strata: Art and Science Collaborations in the Anthropocene" symposium, held at Aberystwyth University in January 2016 (see http://cargo collective.com/artscienceclimatechange/Strata-Art-and-Science-Collaborations-in-the-Anthropocene). At the "Strata" symposium, the pieces were performed and broader discussions were held about the value of science-art collaboration in engaging and educating the public about the Anthropocene and related concepts. Prior to the symposium, in December 2015 we had traveled from the mouth of the River Ystwyth at Aberystwyth to its upper reaches at Cwmystwyth, one of the most important historical lead mining sites in the United Kingdom (Figures 1 and 2A). We then traveled eastward across the drainage divide into Cwm Elan (Figure 2B), where a series of six large dams (Craig Goch, Pen-y-Garreg, Garreg Ddu...
