Artist Marilyn Brame designed the Mountain Wall in 2001 as part of the Terra Native/Celebration of the Native Land Earth Day event. Constructed of concrete with an overlay of mosaic tiles, it educates the community about the city's iconography. Its design features Lake Mission Viejo, the Saddleback Mountains, and the mission bell scrolls and bonnets on city streetlights, portraying symbols integral to the city. Community members worked alongside the artist to illustrate historic emblems of Mission Viejo's history.
