Map Collections in the Marriott Library: Maps on the Web

Numerous map resources are now available online.  These include:

USGS topographic maps

The U.S. Geological Survey, the nation's preeminent mapping agency, is in the process of updating its topographic mapping of the entire country. The new editions of the highly-used large-scale (1:24,000-scale or "7.5-minute") topos will not be printed and distributed to libraries as past printings have been. Instead, they will be accessible online at the US Topo site:

https://nationalmap.gov/ustopo/index.html  

Utah Topographic Maps were updated in 2011 and 2014, and are primarily "photomaps." Earlier editions can be seen as well via the Utah Geological Survey's website at

https://store.usgs.gov/  (Use the "Map Locator & Downloader" and zoom in to the area of interest to find quadrangles to download.)

The latest edition for those topographic sheets that include U.S. Forest Service lands can be found at the Forest Service website:

https://data.fs.usda.gov/geodata/

Click on the image of a US map on the right, then on the next page click "topographic maps." An interactive map will appear, and you can zoom into the area of interest and select a map sheet to download the most recent version of the topo map.

 USGS also has a site dedicated to geologic mapping at: The National Geologic Map Database, a portal to geologic mapping by federal, state, and university agencies:
