"The ultimate app for Geography/Geology amateurs and professionals."
- Mel Martin, TUAW.com

Geology UT is the edition of the popular GIS (geographic information system) covering the state of Utah. It is a self-contained application (no Internet or cellular access required) that contains a vast amount of information about the geology and geography of Utah. Using the iPhone's GPS, it enables you to navigate the state and get a much better understanding of your surroundings, identify geological formations, mines, quarries, rivers, etc....

This release contains 25 layers, which can be combined in any desired way:

- states outlines
- the complete geological map from USGS
- terrain elevation
- zip codes
- almost 7,000 named features (summits, tunnels, cliffs, bridges, etc...)
- fire history
- all earthquakes in recorded history over 3.0 magnitude
- over 13,000 mineral resources
- active mines
- quaternary faults
- old faults
- public land ownership
- hydrologic units
- USGS quadrangles
- township and range
- urban areas
- counties
- hydrology
- roads and major streets
- railroad tracks
- cities and towns
- potassium/argon dates
- state plane zones
- UTM zones
- main aquifers

Each layer contains additional information about each feature. For instance, the geology layer has a description of the unit's name, age range, rock type, and description. Each mine has a name, a commodity, a facility type, and a company name. See our web site for more information about each layer.

There have been a number of improvements since the release of the sister programs covering CA, TX, NY/NJ/CT, FL, WA/OR, AZ and CO. A new layer (Zip codes) has been added. A few bugs have been fixed.
