  • All four scientists in this photo — attending the Lawrence Memorial Grassland dedication in 1974 — chaired our Oregon board of trustees at one time or another. From the left: Ruth Hopson Keen, Stan Cook, Bert Brehm and Jean Siddall.
  • In 1978, through the dedicated efforts of many individuals, our 231-acre Tom McCall Preserve is acquired in the Columbia River Gorge on a site renowned for spectacular spring wildflower displays.
  • Lower Table Rock Preserve, one of two unusual mesas standing high above the Rogue River near Medford, is acquired in 1979. Tom McCall arrives at the dedication of the preserve by landing a plane on top of the mesa.
