If a picture is worth a thousand words, I figure a good map’s worth considerably more. Pictures and words are really apples and oranges, but a map is an apple-orange smoothie.
I started making maps within a few years of arrival in Alaska. This one, of Asx’ée, twisted tree (Eagle River delta) took about 10 days of stippling in 1983.
Today the maps churn out faster—typically several per day. What I’ve lost in patience is gained in efficiency. Modern cartography also allows us to sit on the shoulders of legions of GIS masters, assembling datasets we couldn’t have dreamed of in 1983. Today, at my computer, I can measure the height of any tree between Ch’eet’ Taayí, murrelet fat (Cowee Creek) and Chaas’héeni, humpy creek (Sheep Creek). Or with a click, sprinkle my maps with Lingít place names, their translations (and even an Important White Guy or two).
Below are some of my favorite maps. Some are simple downloadable .jpgs. Some are collections of maps for our favorite destinations, including historical series that can be toggled across time with your keyboard arrows. But increasingly, maps are becoming interactive—leaving the world of static paper and giving the user more control:
Some of my maps are hosted by ESRI’s ArcGIS Online.You can view them in windows within JuneauNature, or directly, full-screen, on ESRI’s site by clicking view larger map.
Why is this more useful than a simple jpg or pdf-based map that I prepare and post? Let’s say you want to customize your own map, of glacial and marine landforms in Shaanáx Tlein, big valley (lower Lemon Creek). Open my surficial geology map. choose view larger map to jump to ArcGIS Online. Frame it just the way you want (mouse roller is best for zooming) Change the basemap to whatever best suits your needs (that 4-square icon on the left). When you’ve got a nice composition, right click and select Take a Screenshot.
Others of my downloadable maps are geopdfs (spatially rectified pdfs for use in navigational apps such as Avenza). These are presented in pairs: a hillshade and an air photo. I like to load both to my tablet for hikes, and often alternate between them depending on whether I’m investigating landforms or vegetation cover. The free version of Avenza holds only 3 geoPDFs at a time. We just have to remember to clean off the old ones and load the new ones before each hike.
So far, the geoPDF collection covers most of the popular local trails, and all of the surroundings of public schools—places where Discovery Southeast naturalists bring students on field trips. If your favorite hike isn’t covered, let me know.
