Geology Raft Trips, Grand Canyon 2007 and 2011,
led by Grand Canyon Sue Tanges

They started out as unofficial San Diego Assocation of Geologists functions. In 2007 we had 27 geologists, biologists, and various other disciplines from Southern California, Arizona, and even McAllen, Texas. A good time was had by all!

I repeated the experience from June 10th to the 17th, 2011! This time we had two full rafts, 28 people in all, including geologists and friends, even 2 doctors, which came in handy!

I want to repeat this "once-in-a-lifetime" experience in June 2014, but...

Thank you Sue!!!

Our fearless leader
