Here is a valiant old horse, "Relámpago," who served as my field vehicle from the fall of 1996 through 1997. His name (which means "lightning") was a bit of a joke, because he was a very slow, even tempered horse, just right for someone like me who obviously had no idea how to ride. We rode both to survey agricultural fields and forest islands, and also to get back and forth between Santa Ana and our study area, a trip of about 12 hours on horseback. In the background, the different colors of grass indicate the outlines of pre-Columbian agricultural fields. The slight rise (in this case about a foot or two) causes some grasses to grow more readily on the higher, drier ground. The small lumps that can be seen on the ground both to the left in the foreground and on fields in the background are anthills and termite mounds. The colors in the photo are a bit off because a long time passed between when the film was exposed and when it was developed.
