Artwork Granite disks, sculpted by Horatio Hung-Yan Law and embedded in the spiral pathway, represent the moon's phases. Various cultural ideas about the cycle of life are captured in the quotations, proverbs, folk sayings, and myths etched in the disks. Benches sculpted with squirrels and salmon by Mufu Ahmed provide seating in the park.
Located in the New Columbia housing development, this park was named in honor of Bill and Gladys McCoy, African-American political leaders who brought attention to the issues of minority and low-income people in north Portland. Gladys McCoy was the first African-American to serve on the Portland School Board in 1970 and as a Multnomah County commissioner from 1979-1984. She was elected as county chairwoman in 1986. Bill McCoy was the first African-American to be elected to the Oregon Legislature in 1973. His senate district covered north Portland and much of northeast Portland.
