We're talking about Chacoan road networks again! A few years ago we interviewed Sean Field. He was doing research on the road networks coming into and out of Chaco Canyon. Sean Field is at it again with another paper but this time he's using Lidar to analyze road profiles. It's an innovative technique and Chris and Paul discuss it on this week's show.
