In Spokane she met the artists Clyfford Still, Guy Anderson, and the Abstract Expressionist painter Carl Morris whom she married in 1940.

[2] Their marriage sparked a life-long partnership between the two artists which enabled them to continuously improve upon their own work through mutual support, without one overshadowing the other in the spotlight.

[1] Except for extended trips to her hometown New York City and in later years Pietrasanta, Italy to cast bronze sculptures, she worked in Portland.

Hilda and Carl's friendship with fellow artist and Northwest School founder Mark Tobey also contributed influences on the styles and symbolism she would explore in her work, including Eastern calligraphy techniques.

Commissioned sculptures by Hilda Morris are in the Seattle Opera House (Muted Harp); Standard Plaza, Portland (Ring of Time);[4] and Pacific National Building, Tacoma, Washington (Sea Myth).
