I am going to be in Zion National Park next week for a couple of days, and am planning to do the Narrows hike along the Virgin River. For those of you who have done this hike, how did you keep your photography gear dry? I have a 40D that I'll be taking with me. Are ziploc bags okay?
Should I worry that much? I've heard usually you only get knee deep in water, but I'm also wondering if it might be easy to trip on something while in the river. Thanks a bunch, as always!
Rainproofing in a backpack: get a heavy duty large trashbag to line the pack with. In case of rain, place gear/clothing inside of trashbag and fold the top down.
Waterproofing suitable for complete submersion: get a "dry bag" (used for canoeing, kayaking, etc; likely available from your local camping/hiking store). This is a rubberized bag designed to be completely waterproof when you roll down the top (like a very sturdy ziploc bag that won't pop open unexpectedly).
I go on long sailing trips with my gear. It goes in aloksaks and then into a backpack with a rain cover. When I go between boats, I carry my gear in one of the dry bags shown.
