The Oregonian reported on October 29, 1970:
All hurdles have been cleared to develop . . . the Tryon Creek area as the Tryon Creek State Park, Gov. McCall’s office announced . . .
The announcement climaxes work that was begun in the early 1960s by citizens who wanted to preserve wilderness areas in the proximity of urban communities. The Tryon Creek area was such a wilderness.
Tryon Creek State Natural Area is the official name of the park. The only Oregon state park within a major metropolitan area, it encompasses Tryon Creek canyon, a second growth forest made up of red alder, Douglas fir, big leaf maple, and western red cedar. Tryon Creek is one of the last unobstructed tributaries of the Willamette River in the Portland area. The park has a Nature Center, trails, and a shelter.
