Detailed blowup of Mount Murphy
FLIGHT LINE Information - flight lines indicated by dark lines, direction
of flight indicated by arrowheads at end of each FLIGHT LINE, TMA # (photo
flight #) indicated by number on FLIGHT LINE, and values in parenthesis
on the flight lines indicate starting amd ending frame #'s.
Control Photos - number at small arrow on FLIGHT LINE indicates frame
#, arrow indicates direction of view (R or L indicates right or left view,
frame # and V in parenthesis indicates vertical view), click on frame #
to display browse photo, thumbnail versions of control photos appear below.

MARIE BYRD LAND CONTROL
Flood Range to Mount Murphy Area
1967-68 Season
Engineers: Jack Harry, Charles Henkle, Lenny Hill, Tom
Taylor
Terrestial survey network employing Wild T-2 for angular
measurements and Electro-tapes for distance measurements.
DKM-3A was used for astro measurements.
BYRD STATION TRAVERSE
1959-60 Season
Engineer: William H. Chapman
Intersected peak positions determined from primary traverse
stations determined by solar position at M258 (Adjusted to Marie Byrd Land
Electronic Traverse of 1966-67-68).
Elevations determined by altimeter traverse based on Byrd
Station elevation of 1530 meters. (The altimetry elevations have been adjusted
to agree with the elevations determined from the Marie Byrd Land Electronic
Traverse of 1966-67-68).
Wild T-2 used for angular measurements.
STANFORD UNIVERSITY TRAVERSE
(KOHLER RANGE CONTROL)
1960-61 Season
Dale R. Reed
Intersected peak position determined from the solar position
of VLF #2 (adjusted to Byrd Station Traverse 1959-60).
Elevations determined by altimeter traverse based on Byrd
Station elevation of 1530 meters.

Horizontal Datum - Positions are based on the Astronomic Position of
Toney Astro determined during the 1967-68 Season.
Vertical Datum - Mean sea level
* A - Astronomical
B- Beaconed - Signal/Cairn & monumented
U - Unbeaconed - Occupied, monumented
O - Occupied, unmonumented
I - Intersected
# Unchecked elevation
** These stations are unidentifiable
+ Quality rating (1:best: 3:worst)
The relative strength of position value shown on the Control Points
Coordinates list for each quadrangle is not an indicator of the accuracy.
It is a reliability number assigned by the USGS based on the number of checks
obtained for that survey point.
As an example, an occupied point with several connections to the surrounding
network is a 1 (highest reliability). Whereas, a point positioned by two
rays intersecting has no check and is assigned a value of 3 (lowest reliability).
(1). Indicates a checked occupied station.
(2). Intersected with 3 or more directions.
(3). Intersected station with no checks - uncertain position - use with
caution.
The Marie Byrd Land survey networks are individual networks with positions
based on astronomic observations taken during the field season of that survey
and were established to provide control for mapping using aerial photographs.
