The 4th International Planetary Dunes Workshop was held in May in Boise, Idaho. About 50 attendees gathered to discuss the latest in image analysis, modeling, wind tunnel work, and field studies of aeolian processes on planets, including Earth. Participants came from as far as Australia and France. As per tradition, we had a field trip halfway through the meeting, during which we visited the Bruneau Dunes, formed in an old, large oxbow of the Snake River. They were wet because of an especially rainy spring, which helped preserve cross beds and made for interesting coloration as the sands on the crests dried out. The pictures are a little out of order, since the first ones are from my waterproof camera. Participants had fun sandboarding, playing with dry ice, and kite cams, among other things. We also visited some thick basalts of the Snake River Plain, with spectacular columnar jointing from rapid cooling.
