In 1906 Rasmus Petersen moved to Redmond (four years before the city’s official incorporation) to begin an agricultural operation. An avid rock collector and notable within the geology community, Petersen amassed a significant collection of local rocks. By the mid-1930s, a sizable rock garden began to appear on his property.
Over the years, acre by acre, obsidian, jasper, agates, thunder eggs, and petrified wood took form in sculptures. By the 1950s, castles, ponds, bridges, villages, and various designs of rocks covered four acres. The property became a tourist magnet, becoming one of Redmond’s best-known attractions.

HPLO anticipates awarding small grant to nominate property to the National Register of Historic Places.
Since Petersen’s death in 1952, the family has operated the rock garden as a museum and roadside attraction. Although the will and the interest are present, the Rock Garden needs major maintenance, a business plan and a publicity campaign to ensure stewardship and funds are available to overcome vandalism, theft, and condition issues. Its significance to the local community – and its unique expression of mid-century roadside architecture – make the Peterson Rock Garden a real gem.
