Wishing I could share from our ‘09 Piaxtla adventure, but unable to for a little while here is one from the Alseseca first full descent in 2006. A photo from our day on “The Avocados” a section which to the best of my knowledge has not been repeated by any other group due to the entrance falls.

Nick Troutman nails a boof.

Nikon D50, Sigma 18-200 @ 46mm 1/1000 F6.3 ISO 800. Post processing in CS4: Exposure +1.5 Clarity +100 Vibrance +50 and Neat Image reduce noise at custom settings.
