Congress No. 6 “Frozen Pasts”
Sciences, humanities and aesthetics of ice through time (honouring Baltazar Ushca).
Quito, 07th – 12th of July 2025 – PUCE-Q
This meeting will focus on the complex interaction of glaciers with biotic and abiotic factors, as well as with human communities through time. In particular, we want to assess their impact on our perceptions, expressed in the complex ideological systems of mountain ecosystem representations. Frozen Pasts 6 stands for the protection of glaciers, for water conservation and for the well-being of a global citizenry.
Scientific committee

Sophie Cauvy-Fraunié
Researcher since 2017 at INRAe (France); Hydro-ecologist, I specialise in high mountain ecosystems. In the field, both in the Alps and the tropical Andes, I collect terrestrial and aquatic organisms along glacier-influenced gradients to quantify the impact of the presence of a glacier on high mountain biodiversity. I am interested in identifying species dependent on glacial conditions and therefore at high risk and characterising the temporal evolution of terrestrial and aquatic communities with glacial retreat.

Congress No. 6 “Frozen pasts”:
Slogan: Sciences, humanities and aesthetics of ice through time
Concept:
This meeting will focus on the complex interaction of glaciers with biotic and abiotic factors, as well as with human communities through time. In particular, we want to assess their impact on our perceptions, expressed in the complex ideological systems of mountain ecosystem representations. Frozen Pasts 6 stands for the protection of glaciers, for water conservation and for the well-being of a global citizenry.
1. Glaciers in the Anthropocene
Jorge Gomez (PUCE) and Olivier Dangles (IRD – PUCE)
As key indicators of climate change, glaciers are experiencing unprecedented transformations in the Anthropocene, with significant implications for human socio-economics and culture, hydrological cycles, and ecosystems. This session seeks to bring together cutting-edge research examining the complex interactions between glacial dynamics and anthropogenic influences. We welcome contributions that address a range of topics, including the historical and anthropological study of glaciers in the anthropocene, physical, social and ecological processes driving glacial retreat across time scales, and innovative approaches to thinking the concept of anthropocene in relation to glaciers. We encourage interdisciplinary perspectives that consider both the scientific and human dimensions of glacial transformation in the Anthropocene, with a reflexion on the dynamical dimension of these processes and how they support (or refute) the concept of anthropocene.
2. Historical dimension and archaeology of ice
María Constanza Ceruti (UCASAL – CONICET and Adina Racoviteanu (IRD – GLIMS)
The session dedicated to the past and present of “archaeology on ice” aims to provide a space for reflection, opinion, dissemination and analysis of case studies related to the emergence, expansion, milestones and current events of high mountain archaeology, glacier archaeology, alpine archaeology and the study of frozen mummies. Such research contributes to the appreciation of the historical and cultural aspects of the high mountain landscape and to the strengthening of local identities. The professional contributions of these sciences, whose approaches and discoveries have opened up new horizons for previously consolidated fields of research (Inca archaeology and landscape archaeology, among others), deserve to be better known by the general public and the international scientific community, and have also contributed to the emergence of new disciplines focusing on the cryosphere. Contributions on archaeological research related to mountains and glaciers in the Americas, Europe, Asia, Antarctica and Oceania are welcome.
3. Transdisciplinarity and indigenous montology of the high mountains
Fausto O. Sarmiento (UGA) and Adina Racoviteanu (IRD – GLIMS)
High peaks have recently been identified as sentient landscapes, whose emotionality is translated by ancestral indigenous knowledge, which sees mountains as special places within its sacred pantheon, either as a refuge (due to inaccessibility); as an origin (due to founding myths); as a physical and mental challenge (due to the effort of ascension); as delirium (due to the hypoxia generated by altitude); as the residence of gods (due to the strangeness of caves, gorges, cracks, pinnacles and fulgurites); as the final resting place (due to the cairns and sacrifices of payment and appeasement to angry gods); or as a source (by inspiration or geomancy, knowledge or eureka moment, illumination or theogony and divine revelation or hierophant and prophetic divination). This mysterious power of the frozen mountains cannot be studied from an individual disciplinary angle, but requires the contribution of numerous sciences, humanities, stories, tales and legends, which allows us to better identify the meaning of our frozen past. Not only high mountain archaeology explains the presence of child mummies on the peaks of snowy peaks, but a variety of approaches that contribute to the better interpretation of the traces of the climate, of the ancestors, and their respective traditions and legends about ice, water, waterfalls, rivers, rocks, dew and aquifers converted into offerings, valuable resources, heritage sites, identity elements and connection with the immaterial beings of the high mountains. With a bias of transdisciplinarity, various case studies will be analyzed in which nature-culture hybrids allow for conceiving snow-capped peaks as cultural landscapes with an important ecological legacy.
4. Water in all its forms: an interdisciplinary subject of study
Sophie Cauvy-Fraunié (INRAe) and Carmen Fernandez-Salvador (USFQ)
Beyond the Western and modern conception of water as an element of nature or as an indispensable resource for the development of societies, different cultures at different times in history have emphasised the symbolic value and capacity for meaning of rivers, lakes and glaciers. In addition, different peoples have conceived of water as a living being with its own agency or with a kinship relationship. In all its forms, water is also the habitat of a multitude of life forms, creating spectacular and fragile ecosystems. This session invites us to propose definitions and descriptions of water in its different forms and states, according to the discipline studied, and to reflect on alternative ontologies that recognise correspondences, continuities and relations of reciprocity with the natural environment.
5. Ecocriticism of Glaciers: Science and Aesthetics in the Imaginary
Kathrin Schneider (PUCE) and Carmen Fernandez-Salvador (USFQ)
This section explores the intersection of science and cultural representations in understanding glaciers, focusing on their representation in literature, art and media – from poems and novels to the Disney film Frozen, landscape paintings and art installations. As symbols of both environmental stability and vulnerability, glaciers occupy a unique place in the human imagination, embodying both beauty and danger in our paradoxical relationship with them. From an ecocritical perspective, glaciers are more than natural phenomena: they raise issues of climate change, ecological fragility and human responsibility. Aesthetic representations of glaciers can aim for the sublime, emphasising their beauty and awesome power, but they can also remind us of their rapid loss due to global warming, making them potent symbols of environmental crisis. Scientific texts can also have aesthetic qualities that resonate in cultural narratives. Bringing together the sciences and humanities, this session highlights the need to rethink our relationship with nature and recognise the global significance of glaciers in both ecological and cultural contexts.
6. Glaciers as symbolic places of encounter
Alden Yépez (PUCE) and Olivier Dangles (IRD – PUCE)
Esta sesión pretende explorar los glaciares no sólo como entidades físicas, sino también como espacios emblemáticos que escenifican valores positivos y negativos de sociedades pasadas y presentes. Nos interesan especialmente las contribuciones que examinen los glaciares como lugares de encuentros culturales, religiosos, científicos y geopolíticos. Serán bienvenidos los estudios sobre la intersección de la historia cultural, el turismo, la conservación y el cambio climático en lugares específicos de estudio de glaciares de todo el mundo en los que se haya llevado a cabo un estudio exhaustivo e interdisciplinar. Estos encuentros abarcan desde la interacción de elementos naturales y culturales hasta la convergencia de actores humanos y no humanos, incluidos científicos, comunidades indígenas, gestores, políticos y turistas, así como aspectos existenciales y cognitivos de los glaciares. Al abordar los glaciares como lugares de encuentro polifacéticos, esta sesión pretende ampliar nuestra comprensión de su importancia tanto en el mundo natural como en la experiencia humana.
