[1] Marquam Nature Park is in Southwest Portland in the Tualatin Mountains, also known as the West Hills, and has several miles of hiking trails.

The park's entrance features a shelter with interpretive displays and maps.

[1] The volunteer organization called Friends of Marquam Nature Park formed in 1968 after neighbors of the park successfully prevented housing development on Marquam Ravine.

[3] In 2013, Friends of Marquam Nature Park and the Regional Arts & Culture Council funded a mosaic project for one of the shelter's walls.

The project cost $17,600; assembly began in August, and the dedication took place on September 28, 2013 following its completion.
