Maya Settlement Patterns and Land Use in Buena Vista, Cozumel, México
FAMSI © 2004: Adolfo Iván Batún Alpuche Maya Settlement Patterns and Land Use in Buena Vista, Cozumel, México Research Year: 2003 Culture: Maya Chronology: Post Classic Location: Cozumel, México Site: Buena Vista Table of Contents Abstract Resumen Introduction Project Goals Research Design and Methods Preliminary Results Microenvironmental Zones Main Transects Transects Limiting Quadrants Selected Areas Soil Profiles Summary and Conclusion Acknowledgments List of Figures Sources Cited Abstract The Buena Vista Archaeological Project is a study of postclassic Maya settlement patterns and land use on the island of Cozumel, México. Field work carried out in the site during the months of June–August 2003 was sponsored by the Foundation for the Advancement of Mesoamerican Studies, Inc., (FAMSI). Previous archaeological research in Buena Vista had focused in a central area of seven hectares and reported the existence of an extensive wall system and platforms at the site which was interpreted as a storage center for exchange and resupply transactions. In this interpretation, the platforms supported perishable structures used to store trade commodities, and the wall system was built to protect these trade goods from possible pirate attacks (Sabloff and Rathje 1975, Freidel and Sabloff 1984). However, the nature and extension of the wall system around the central area had not been investigated in detail. The research objectives of this project were to analyze the Buena Vista settlement pattern following a settlement ecology model (Stone 1996, Killion 1992), which seeks to understand the relationship between population and agricultural practices in an ecological setting. The project followed a program of surface survey and mapping of the wall system, related structures, and natural features located in an area of 4 km2 around the center of the site. -

Visionary Counting on Unmanned Vehicles
Visionary Counting on Unmanned Vehicles By Rich Tuttle Bill Stone, the founder of Stone Aerospace, has a vision—several visions, in fact—and unmanned vehicles play a part in a number of them. His Austin, Texas-based company developed and built the DEPTHX robot that last May conducted the first comprehensive exploration of the world’s deepest sink hole, El Zacaton in Mexico. It brought back enough data to keep scientists enthralled for some time. An unmanned system based on DEPTHX (DEep Phreatic—meaning underwater cave—THermal eXplorer) will be tested in Antarctica beginning next year to help determine the suitability of such a device to meet, in about 20 years, what’s been called the ultimate robotic challenge: exploring the ice- covered ocean of Europa, a moon of Jupiter. Scientists believe there’s a high probability of detecting the first life off Earth in that remote and ancient sea. That's one vision. The challenges would fill a book: melting through many kilometers of ice just to get to the ocean, for instance. That will be addressed in the Antarctica experiments. But DEPTHX does seem to have demonstrated the possibility of clearing two other key hurdles—surviving in a three-dimensional, unexplored environment without external navigation aids; and carrying out science experiments autonomously. DEPTHX's abilities are two generations beyond those of the Spirit and Opportunity rovers on Mars right now, Stone says in an interview. Every move of the Mars vehicles is based on a carefully prepared script. But, Stone says, “in the case of Europa, it can’t be that way.” The computer brain of a Europa probe would have to be wired to achieve “global” objectives, he says. -

Cenote Calavera's Geohistory Isabella Fernandez Cenotes Are Arguably
Cenote Calavera’s Geohistory Isabella Fernandez Cenotes are arguably the most popular natural wonders of Mexico’s Yucatan peninsula and understandably so. Cenotes are sinkholes that result from collapsed limestone bedrock to reveal groundwater and underground caves that home various forms of life. One of the most popular cenotes is Cenote Calavera or “Skull Cave,” named aptly after it’s skull-shaped opening. Cenote Calavera is an anchialine system in that groundwater is land-based but has subterranean connections to the ocean making it a part of a coastal aquifer system where entering rainwater floats upon saline water. With this system, various flora and fauna can survive in the caves. Cenote Calavera also holds incredible cultural importance as ancient Mayans believed that cenotes were gateways to the afterlife and considered them sacred wells where religious ceremonies were held. Cenote Calavera is especially recognizable because of the qualities that make its resources preservable. Sites that allow for groundwater recharge and stormwater management are particularly eligible for preservation (International Union for Conservation of Nature). Opportunity for tourism and recreation also contributes to a site's preservability as it brings revenue to that location (United Nations Environment Programme). Cenote Calavera’s complex water system and support of life-forms as well as open diving tours make it particularly unique. Of course a site's significance comes partly from other aspects of its value. The condition of its resources is an important factor as well as overall aesthetic and rarity. Cultural importance also plays an important role as mentioned above. Tourism rates help greatly, too, and Cenote Calavera is abundant in tourists looking to explore the caves. -

Of course, after committing two-hundred and some odd pages to the discussion of my research over the last five years, I have few words left for the one section that will probably be read the most of any other in this dissertation. Additionally, recounting the memories of all the love and support which I have received from so many people brings tears to my eyes every time I have tried to work on this section. My cup runneth over. I have written this acknowledgments section one hundred forty-three times; yes, I have been counting. I can not simply list every person who has participated in the success of this work, as the list would be longer than the dissertation itself. So, I must restrict myself to acknowledging only those whom have truly made this all possible, and at times, very worthwhile. -

Rest of the Solar System” As We Have Covered It in MMM Through the Years
As The Moon, Mars, and Asteroids each have their own dedicated theme issues, this one is about the “rest of the Solar System” as we have covered it in MMM through the years. Not yet having ventured beyond the Moon, and not yet having begun to develop and use space resources, these articles are speculative, but we trust, well-grounded and eventually feasible. Included are articles about the inner “terrestrial” planets: Mercury and Venus. As the gas giants Jupiter, Saturn, Uranus, and Neptune are not in general human targets in themselves, most articles about destinations in the outer system deal with major satellites: Jupiter’s Io, Europa, Ganymede, and Callisto. Saturn’s Titan and Iapetus, Neptune’s Triton. We also include past articles on “Space Settlements.” Europa with its ice-covered global ocean has fascinated many - will we one day have a base there? Will some of our descendants one day live in space, not on planetary surfaces? Or, above Venus’ clouds?
