Subject: Progress Letter Report for period 1 July 1973 to
31 July 1973
Title: Geologic and Mineral and Water Resources Investigations
in Western Colorado, Using Skylab EREP Data (Contract
No. NAS 9-13394, Proposal No. EREP 380)
INTRODUCTION
The primary objective of the CSM Skylab Program is to analyze
EREP data for geologic information. To this end, the research
has been subdivided into the following tasks:
Task I. The PI shall assist NASA/MSC in mission planning
activities related to the proposed investigation.
Task II.
Task III.
Task IV.
The investigator will screen all EREP data obtained
over Colorado and will select frames for detailed
study.
The investigator will prepare photogeologic maps using
selected S-190 photographs, and will analyze them to
determine what geologic information may be contained
in them.
The geological interpretations obtained in task 3
will be compared to interpretations obtained from
S-192 imagery, and to interpretations made from ERTS-I
imagery.
Task V. The geological interpretations will be verified by
means of interpretation of aerial photographs,
published geological reports, and field observations.
Task VI. The investigator will prepare recommendations for the
optimum type, scale, and resolution of imagery to be
used for studies of regional geology and exploration
for mineral deposits and water resources.
Past Month's Activities
EREP data product requirements were defined and transmitted to

the PIMO.
Work continued on the final geologic map and report of the
Bonanza Regional Geology Test Site. The final product is now
about 75% complete.
Investigation proceeded on making a photo-mosaic of the relief
maps of Colorado. Several problems of technique have been
overcome and a final product is forthcoming.
Evaluation of ERTS imagery over Skylab tracks in Colorado continued.
Comparison of a regional map of Eocene faulting and drainage in the
intersection of Skylab Tracks 30 and 48 with image interpretation
revealed that approximately 50 percent of the mapped features
were expressed as linears.
The study of shadow enhancement of linears continued with
extension of the theory of D.U. Wise and application to photo-
graphs of selectively illuminated relief maps. Most interesting
are the aligned, discontinuous linears revealed subparallel to
the illumination direction. The topography underlying the segments
often is not as strongly parallel, and the associated linears
will not persist at other illumination directions. The problem
was further studied by producing a map of randomly generated
linears and evaluating the significance of the trends. Several
trends were apparent to the eye and were generally mildly
significant in the statistical test.
Planned Activities for Current Month
Progress of Skylab 3 will be monitored, with input to PIMO where
appropriate.
Skylab 2 data will be indexed and screened, as received, and
geologic photointerpretation will begin.
The BRGTS study will continue toward completion.
The study of lineaments and geologic fracture patterns will
continue, probably with the initial correlation to EREP
photography.
Travel
No travel costs were incurred during July.
Planned travel for August consists of one trip by PI to the San
Juan (Tracks 34, 30) field area.
