Second sinkhole appears at Cape Kiwanda on Oregon coast

Another large sinkhole has formed at Cape Kiwanda State Natural Area on the Oregon coast. It’s the second one to appear on the headland in the span of about four months.

The new sinkhole is located in the lower northeast corner of the dune and sits only a few inches away from the first one, which visitors had reported to the Oregon Parks and Recreation Department in January 2023. The first sinkhole initially measured 20-feet wide by 15-feet deep. The second sinkhole measures about 10-feet wide by 30-feet deep and appears to be more shallow.
