This looks interesting:
The First International Planetary Cave Research Workshop: Implications for Astrobiology, Climate, Detection, and Exploration will be held October 25–28, 2011, at the National Cave and Karst Research Institute <http://www.nature.nps.gov/nckri/> , 400-1 Cascades Avenue, Carlsbad, NM 88220 USA (phone: 575-887-5518). The workshop will also include a one-day field trip. The First International Planetary Cave Research Workshop is a follow-up to the 2008 Lava Tube Workshop held in Grant, New Mexico, which brought together researchers with interests in lava tubes from diverse backgrounds, ranging from image analysis to modeling to robotics. The workshop is the first in a continuing series of meetings that are intended to promote the exchange of knowledge and ideas between planetary and terrestrial scientists interested in cave exploration and research across the solar system. In recognition of the broad scope, interdisciplinary nature, and strong international interest in this topic, the participation of any interested scientist with relevant theoretical, experimental, or field experience is strongly encouraged. The first announcement is now available on the workshop website: http://www.lpi.usra.edu/meetings/caves2011/
