With this app, in the palm of your hand you have a complete United States Geological Survey topographic map for Zion National Park. Begun in 1879, and the result of over 100 years of work, the USGS topo maps are the gold standard in reference maps.
The map is completely included in the download, and no further Internet connection at any time is required.
The scale of the map on the downloaded app is approximately 1:15,000. This is a greater level of detail than the standard USGS 7.5 minute printed map, which is on a scale of approximately 1:24,000. Our app also adds a level of magnification to help with reading the small print.
Additionally, what you can do with our app that you cannot do with a printed map is have your current GPS location plotted directly on the map. This does not require a cell connection, and means that, as long as you have line-of-sight to a GPS satellite, you can see where you are on the USGS topo map at any place in the park.
To learn more about how to use the topographic map in this app, please read the How to Use this App section after installing the app.
More Detail, and Trail Overlays ======================
This Zion National Park Topo app contains a single resolution of the topo, with no trail overlays. If you are going to do any kind of hiking, we recommend you download our full Zion National Park app. It contains dozens of hiking trail maps. Then, for topo maps with even greater detail, install the optional USGS Topo Map. This provides three levels of resolution, down to a scale of about 1:4,000. The full Zion National Park, combined with the USGS Topo, is the best pocket guide you can take with you when hiking. Best of all, once the app and topo are downloaded, you never need an Internet connection to use them.
