My first stop was Xibalba Maya Site. It is a recreation of the Temple of the Inscriptions, a Maya ruin in Palenque Mexico. It is a picturesque site with a large Mayan temple and a smoking volcano in the background.
At the top of the temple is a museum with a series of 8 vases and 2 photos. The artifacts had a link to both an artifact description and its entry in the Maya Vase Database. As of today, it has had 97 visitors. It looks like it is part of a larger continent of 11 islands that share a similar geography. There was a lot of geography to explore - I got stuck in the volcano and flew through a lightning storm. I had seen mention of the site on the Second Life Educators List (SLED) According to the list, it was supposed to have underwater caves you can explore, but I was unable to find them or the site has changed. It was a pleasant stop and is worth a quick visit if you like Mayan archaeology.
