High-resolution GeoPDF pair for field navigation around inner Áak’w Tá, little lake bay (Auke Bay). Includes Áak’w, little lake, and educational facilities at Auke Bay Elementary (AB) and UAS: Rec Center (UR), Housing (UH) and Egan Library (EL). 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 and hiking trails, and our wetland units from the CBJ wetland survey project. Thick blue lines are “subsheds,” also mapped during that project. On this bare-earth image, with forest cover digitally stripped away, you can easily make out wave-cut escarpments from higher sea level in the early Holocene. Most prominent is a sudden step-up at 230 feet—same level as the dominant riser on northeastern Sayéik, spirit helper (Douglas Island)

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.
