I. Overall Status:
1. Plans to acquire high altitude black and white low sun angle photography
along track #20 were implemented on September 18, and October 17th with
overflights by NASA Ames U-2 aircraft. The two flights were started at
10 and 20 degree sun angles respectively and both covered the entire
Winnemucca 1:250:000 AMS Sheet. The flights required about one hour
each to cover the area during which time the sun angle increased by about
10 degrees, which means that the 28 degree sun angle coverage as seen
from the B/W, S-190B photography taken on August 12 was duplicated by
the airborne systems. The aircraft employed two cameras, with two dif-
ferent focal lengths one 24" and the other 6". The 6" camera provided
full coverage with 60% forelap and 20% sidelap at a scale of 1:110:000
while the 24" camera provided an eight mile swath down the middle of
the four flight lines at a scale of 1:30:000. Both missions were flown
without a cloud in the sky. The differences in scale and sun angle
provide an excellent format for direct comparison with the Skylab data
and are being utilized in structural and geomorphic studies.
2. All colored products from the S-190A and S-190B have been received and
sent out for duplicating by an outside contractor, none of which have
been returned to date.
J. Expected accomplishments for the next reporting period.
1. Work on lithologic and structural studies will be emphasized using
color and low sun angle photography.
