One Of The Oddest Geological Wonders Is Located Right Here In Portland
Some of the oldest rocks in Portland are thought to be housed on this ancient island called Elk Rock. Formed from a volcanic eruption over 40 million years ago, this island was created by lava flows and features seven distinct habitats in its 13 small acres.
Wetlands, forest and grasslands can all be found at this beautiful natural area, teeming with trails for exploration.
Made up predominately of Waverly Heights Basalt, these large and jagged rocks predate Columba River Basalt, a more common rock in the area thought to be 10 to 25 million years old.
Six owners later, Portland businessman Peter Kerr acquired the property from the Rock Island Club in 1910. At the time the island was home to a dance hall.
Kerr gave the land to the city with one requirement: it must remain in its natural state. The park was dedicated in 1954 and has remained a wilderness haven for decades.
