Very far from the desert, but still interesting, informative, and full of adventure, you may be interested in reading about archaeological investigations during the 2003 and 2004 field seasons in Belize, Central America. Most of the information, including the online field journal, is from 2004. During that summer I drove across Mexico to southern Belize to spend 3 months in the jungle.
Although the BEMEP (Belize Electromagnetic Explorations Program) website is no longer active, the site is archived and can be viewed.
