A couple years ago I did a brief consulting assignment through Indiana University, and I just found a ton of photos from that trip that I never shared on Goboogo. I am going to cycle through them over the next few weeks. Guatemala is an incredible country, extremely worthy of a visit and a couple week stay.
One of the coolest parts of my trip to Guate was visiting Lake Atitlan. The lake is located in the Guatemalan highlands and is over a thousand feet deep. It is flanked by 3 volcanos and several Mayan villages.
The lake was once thought to be showcased an angling Guatemalan show piece, so they stocked it with all kinds of non endemic fish, like the Black Bass. Of course, terrible things happened. This little bird went extinct (Atitlan Grebe), and 2/3rds of the lakes endemic fish disappeard. Bummer.
Panajachel is a bigger village on the lake and has decent tourist infrastructure. It was also a popular hippie hangout in the 60's.
