Ross and Mike and our custom pontoon raft made it to Cartersville on Friday before we gave them the weekend off to attend to some business at home. The James has been low, and that’s slowed our efforts to create the first-ever 3-D image map of an entire river, but we’ll be pressing again this Monday. It’s less than 60 miles from Cartersville to Richmond. Then it’s about 100 miles on the tidal James to Norfolk. We’re getting to close. (If you’re unfamiliar, click here and here to read more about the journey. And here to follow it on Twitter.)

The above video is of Ross and Mike taking the boat through Balcony Falls near Glasgow. Look at how she glides over that whitewater! (Thanks to Bill Wise for sharing the video.) Those other canoeists in the shot are from the JRA’s James River Expedition.

And while the boys are out on the boat, Ryan is back in Richmond processing the images from up in the mountains. Here are a couple of examples.
