Huge thunderstorm in western Grand Canyon

A highlight in anyone's life, particularly a geomorphologist's. More proof that digital video can really complement geologic field work. Love that waterproof camera.

Resurrection / Superposition Rapid, Colorado River

In an ironic geomorphic situation, the Colorado River has formed a new rapid downstream from the mouth of the Grand Canyon near Pierce Ferry. Here, recession of Lake Mead has (obviously) induced incision by the river. The river adopted a new course that traverses some resistant beds in the Muddy Creek Formation. This video chronicles the vagaries of this rapid.

Love my Pentax Optio W60!

I splurged on a waterproof camera before a long trip down the Grand Canyon. Aside from assuaging my fear of taking pictures in the rapids, it also provided a great opportunity to film a ride through a classic river rapid wave train with large standing waves. Critical flow anyone?

Who needs a waterproof camera? You do.

I have just returned from my grand hiatus and have lots of proof that waterproof cameras kick proverbial a*s. For example, check out this little video (with audio, no less) of bedload transport in Travertine Grotto:

Grand Hiatus

Greetings subscribers (all 3 or so of you). I am on hiatus for the next 3 weeks. I will be trying out my new waterproof / dustproof Pentax camera on a trip down Grand Canyon from Phantom Ranch to South Cove. Will be sure to provide some follow up. For now, check out some bedforms on the floor of the shallow part of Lake Tahoe. I am confident the camera will work on the river...
