text: Confirmed the park as closed from Streetside imagery, which shows a fenced off area that is in clear disrepair. No indications of a park sign. The only record I can find is https://www.digitalarchives.wa.gov/DigitalObject/View/4236D630E38D65EF048B71E90C262194. This indicated that at least in 1941, there was a Rock Island State Park. I can't find any other records, though. Very strange.
