The unique cave which you see here was named "Sunny Jim" by Frank Baum of Wizard Oz fame. The opening bears a resemblance to a cartoon character Sunny Jim who was a mascot for the British Force Wheat cereal products in the 1920's.
Fossilized shell and water level marks indicate that the ocean's might was busy for 200,000 years boring this cave into rock and sandstone. The beautiful colorings are mineral deposits varying from the red of iron oxide, the black, grays and yellows of vegetable matter to the pinkish purple of iodine in the kelp.
Two years work by laborers hired by Gustav Shultz in 1902 and 1903, using pick and shovel, created the tunnel. Several years after its completion 145 steps were built into the lighted tunnel where visitors can still descend and enjoy the wonders of Sunny Jim.
