NOAA describes Lidar – Light Detection and Ranging- as a remote sensing method used to examine the surface of the Earth. My brother, http://eyeonlakeo.com, Todd Thurlow, shared such an image, of South Florida, during the October meeting of the Rivers Coalition http://riverscoalition.org. Looking at the image, Todd noted that the elevations displayed have not changed in over 5000 years. One can clearly “see” where the water used to go and not go. The tiny St Lucie River on Florida’s east coast was isolated from Lake Okeechobee by a ridge only to be connected to the lake in 1923 by the C-44 Canal -that can also be seen in this image. This why on the east coast we stand strong in saying #nolakeo. We never were and prefer to be unconnected.
