Oaxaca's cuisine is considered to be one of the finest and elaborate in all of Mexico. Oaxaca is known as the "land of the seven moles," because of its seven distinct multispiced mole sauces. Oaxaca is also famous for its cheeses and meat dishes. The weeklong festival offers a number of hands-on cooking opportunities taught by four local chefs. Other events include wine-tasting, chocolate-making, a coffee mill tour, Mezcal (an alcoholic drink derived from the maguey cactus) tasting, nature walks, archeological tours and trips to craft villages and markets. Travel 360 is marketing a package priced from $598 per person, double, excluding air fare. Accommodations range from the intimate Hotel Victoria Oaxaca to the five-star Camino Real Oaxaca.

The Zapotec was one of the most important cultures at the time of the Maya. The team found the remains of three persons, including one who was interred seated and wearing a single green stone bead, both signs that the occupants of the complex were privileged and that those interred in the tomb held high status. The tomb included three wall niches filled with ceramic vessels. Twenty-five vessels dating to the latter part of the Classic period (AD 500-700) also were found. A brief report of the tomb's discovery will be published in the September/October issue of Archaeology Magazine.CORRECTION: Avalon Resorts owns and operates five resorts in Mexico and Panama -- the Avalon Grand and Avalon Baccara resorts in Cancun, the Avalon Excalibur in Acapulco, the Avalon Reef Club on Isla Mujeres, and the Avalon Grand in Panama.
