Ask A Question


Just about anything about the river portion, including rafting, camping, preparing for a raft trip, private trips, interpretation (geology, human history, etc), publications, Glen Canyon dam. I`m also willing to answer general questions about the South and North Rims, but primarily can be a resource to refer people to the right source.

Experience in the area

Grand Canyon raft guide since 1978. Author of "Dancing on the Edge", set in the Grand Canyon. Recovering MBA. Former radio and television host. Speaker, author, photographer, consultant/trainer. I love supporting people in overcoming self imposed limitations. I have two very inspiring multi-media presentations on the Canyon.

What do you like about this subject?

I am passionate about the impact the Grand Canyon has on people who visit. As a possibilities coach, I help people expand their appreciation for who they are

What do you still hope to achieve/learn in this field?

To be "The Grand Canyon Guy", and continue to learn more about human potential. Also to use the beauty and power of the Canyon to make people around the world more aware of our need to preserve our natural treasures.

Something interesting about this subject that others may not know:

Studies have shown that rafting on the Colorado River through Grand Canyon is more dangerous than bowling and less dangerous than golf (injury rates). The Grand Canyon is no more than 50 million years old, and perhaps only 6 million. The oldest rocks are 1.7 billion years old.

Something controversial or provocative about this subject

The Glen Canyon dam was built to save Lake Mead from filling up with silt. It is the only major US dam built into sandstone, which acts like a sponge. It could eventually fail from the pressure of the water, or sand waves slamming up against it. Some people, even PhD geologists, who interpret the bible strictly, place the geology of the Canyon in a 6000 - 9000 year time frame.
