High-resolution GeoPDF pair for field navigation at the confluence of Asx’ée/L’ux, twisted tree/milky water (Eagle and Herbert rivers). Includes State Park, Methodist and Scout camps. In apps such as Avenza, on your phone or tablet, you can see your GPS/cell-triangulation position on this image, and lay a track.
First choice below is a LiDAR-derived bare-earth hillshade with modeled streams and 10-foot contours. Other layers, exported from ArcMap, are named roads, hiking trails, and our wetland units from the CBJ wetland survey project. Thick blue lines are “subsheds,” also mapped during that project. The bold blue line at Extreme High Water continues far up both rivers. Upper limits of the green tint at 32 feet show maximum tidal incursion at peak Little Ice Age.
The second choice is a 2013 orthophoto with overlain streams and trails. More information on geoPDFs and use of Avenza is at Media types>Maps&geoPDFs., and at Tools>Field navigation.
