Cascadia Day is a day chosen to join together to help celebrate and raise awareness of Cascadia, meet our neighbors, and discuss and plan how we are going to positively create change here in the Pacific Northwest. Raise your flag, wear your patch, and join fellow Cascadians, building Cascadia as a positive force for change.
Why May 18th?
May 18th is the anniversary of the Mt. St. Helens eruption, chosen by former Seattle University professor David McCloskey as a day to represent Cascadia because of it's visceral reminder of the dynamism of our region. We live under massive forces that shape our world, in a region defined through it's geography, geology and topography - and we are all a part of these processes.
