File Breakdown by Spatial Reference (Detailed) 

2 files use the Projected Coordinate System 'NAD83 / UTM zone 10N', measured in 'metre'
These files use the vertical coordinate system 'PROJCS["NAD83 / UTM zone 10N"', measured in 'GEOGCS["NAD83"'
The full text of this spatial coordinate system is as follows:
