Understanding the current condition of Glacier Bay's natural resources helps park managers to determine priorities, make management decisions, and communicate with our partners and visitors about how we can protect this environment. Explore the sections of the Natural Resource Condition Assessment PDF to dive deeper into the natural heritage of this living laboratory and discover what we found. Note: This is a 20MB PDF file.
