Not far away in another grove of eight trees is a sculpture of three servicewomen caring for a wounded soldier – the Vietnam Women's Memorial.
Dedicated in 1993, it honors the contributions of women in the Vietnam War.
In the sculpture, a nurse sits on sandbags holding a wounded serviceman while another searches the sky for help – perhaps a helicopter airlift. A third kneels behind the sandbags, holding a helmet in her hand.
Artist Glenna Goodacre said the young serviceman is saved by the actions of these women - in a monument to the living.
