My first inclination of these two rocks is that they are great skull simulacrum, but then I started wondering if maybe Mother Nature was responsible and perhaps we should credit these to her. No matter which way you think it should be I still need to give credit to the ones who captured the images and shared them with us. The first is from Brad of Kuching, Sarawak, Borneo, Malaysia who found this awesome sight at the Mulu National Park. The second comes from Jen Craniac of Peru, IL who discovered this landmark at the Cave Of The Mounds near Blue Mounds, WI. These both seem like great destinations to visit, even without their skulls. Take a hint from Brad and Jan and get out there and explore your world. If you happen to find a skull simulacra then share it with us so that we can spread the wealth. Thanks for doing just that, Brad and Jan!
