Photos from my August 2017 visit with Lawrence Crowder in Alamosa, Colorado, as he raked and baled alfalfa. A couple of months earlier, in June, I had caught up with the NASA Airborne Snow Observatory team in Grand Junction, Colorado, from which they based flights over the Rio Grand River’s headwaters. Crowder’s alfalfa depends on that water.


And a video (this with the original Twin Otter aircraft and Teledyne Optech lidar, later replaced with a Riegl):
