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

What if you could hold all of Texas in the palm of your hand?

Geology TX is the Texas edition of the first GIS for the iPhone. It is a self-contained application (no Internet or cellular access required) that contains a vast amount of information about the physical geography and geology of Texas.

This release contains 29 layers, which can be combined in any desired way:

- states outlines
- the complete geological map from USGS
- terrain elevation
- bathymetry (ocean depth)
- USGS quadrangles
- quaternary faults
- older faults
- all earthquakes of magnitude 3.0 and above
- urban areas
- counties
- hydrology
- roads and major streets
- all train tracks
- all cities and towns
- active mines
- potassium/argon dates
- state plane zones
- UTM zones
- vegetation zones
- river basins
- aquifers
- public lands
- zip codes
- fire history
- ecological regions
- hydrological units
- named features
- mineral resources
- annual precipitation.

While this is a professional-grade tool, it can be enjoyed by anyone who likes to understand the world around them.
