Elk Rock Island Explained
Elk Rock Island is an island on the Willamette River in the U.S. state of Oregon.[2] The 12- to 13-acre (4.9- to 5.3-ha) island, formed 40 million years ago by a volcano, was given to Portland by Peter Kerr in 1940.[3] [4] [5] The city of Milwaukie took ownership of the park in April 2016.[6] The island is accessible via Spring Park.
Ecology
The island contains deciduous forest, mixed evergreen-deciduous forest and perennial graminoid vegetation.[7] [8] It is one of the last stands of the Oregon White Oak.[9]
