There is one tab-delimited data file with 3 header lines.
	MR_XS_Coord_07.xls


Horizontal coordinate information is referenced to the North American Datum of 1983 (1999) (NAD 83[99]),
and vertical coordinate information is referenced to North American Vertical Datum of 1988 (NAVD 88),
based on occupation of NGS control point U95RESET (PID AB7734) (National Geodetic Survey, 2006).  
Geospatial coordinates are reported as projected in UTM Zone 12 North to two decimal places.


File MR_XS_Coord_07.xls is ground-surface coordinates at cross sections in 2007.  Fields 
from left to right are:
	Cross section is number of cross section (increasing upstream)
	Station is distance in meters along cross section from left(facing downstream) to right
		head pin -- in a reoccupation stake-out-to-point mode this refers to original point
	Offset is distance in meters downstream from line between headpins  -- in a reoccupation
		stake-out-to-point mode this refers to original point
	Point Name is unique point identifier of point being sampled
	Northing is UTM 12 N coordinate (NAD 83[99])
	Easting is UTM 12 N coordinate (NAD 83[99])
	Elevation is vertical coordinate (NAVD 88)
	Month is numeric month of sampling
	Day is numeric day within month of sampling
	Year is year of sampling
	Hour is numeric hour (24-hour format) of sampling
	Minute is minute of sampling
	Stake-to-point name is point name of point being reoccupied
	Stake-to-point delta is distance in meters between point being sampled and original point
		being reoccupied 
	Notes is description of special circumstances
