This image shows Cave Point, the location illustrated in an earlier posting from this week, but this time from the lake side, giving a better view of the actual cave.
The description states:
CAVE POINT, SOUTH OF JACKSONPORT
Door County, Wisconsin
—Cave Point Park is a popular tourist destination for travelers from many states, but is sometimes overlooked as it is a county park and not a state or national park. The eroded limestone shoreline gives the place it’s name.
This card is dated 1963.
