Parallels of ecological impacts of climate change in Arctic and Andean regions are revealed on glaciological research expeditions in Chile, Alaska, Iceland and Peru. Cresta Alta follows the commitment of scientists who travel deep into the wilderness to gather field data that informs our collective understanding of climate change impacts on our planet. Sustainability initiatives in these same locations offer insight into the potential for viable alternatives and solutions.

The Cresta Alta Film Tour is engaging audiences throughout the US with arts councils, colleges, high schools and museums at events produced by The Risan Project. The 2025 tour features Risan Media's expedition-based climate change documentary film titled, Cresta Alta, that chronicles a journey to Alaska, Iceland, Chile and Peru to document glaciological research expeditions and sustainability. The screenings are followed by a discussion/Q&A with producer and director, Todd Anders Johnson, that connects Cresta Alta's global environmental messaging to local and regional environmental movements.
