Searching for photos of established Swales

Hey All,
I'm currently writing a proposal to add swales into rangeland restoration research to see if this permaculture system might prove useful to the scientific community. Does anyone out there have photos of their established swales they would share with me? Aerial photos would be fabulous (even from Google Earth), but anything would be helpful. We're in Western Montana, so photos from similarly arid climates would be a bonus.

Thanks, Miles. Unfortunately I'm still unable to find photos of established swales. There are are a lot of folks posting ideas and pictures of newly dug swales, but I'd love to see something that's been in for a couple of years.
