About Us


We are an independent, non-profit organization not officially affiliated with Crater lake National Park or the National Park Service (NPS), as a "park partner". We are in the process of obtaining our tax-exempt non-profit status.


Many of our friends are ex-Crater Lake National Park researchers, natural historians, and long-time visitors who are passionate about getting the message out to all visitors concerning Crater Lake National Park's unique natural and cultural history.
