Many organizations support Crater Lake National Park and none are strangers to the Crater Lake Trust.  We each support one another’s efforts which in turn support Crater Lake National Park and make it an amazing place to visit.

Crater Lake Natural History Association

The Crater Lake Natural History Association is a non-profit organization, established for the benefit of Crater Lake National Park and Oregon Caves National Monument and Preserve under a memorandum of understanding with the National Park Service.   The mission of Crater Lake and Oregon Caves Natural History Association is to be an active partner with the National Park Service to inspire public understanding and foster preservation of natural and cultural resources at Crater Lake National Park and the Oregon Caves National Monument.
