Once called the “Straight Wall” and believed to be a long,
abrupt cliff, the “Straight Fault” is one of the Moon’s most
prominent fault lines, running 115 kilometers from end to
end. Far from being an abrupt drop off, the Straight Fault
is actually a gradual slope, rising about 300 meters from
the foot of the slope to the top. The best time to view the
Straight Fault is around sunrise and sunset, local lunar
time, when the shadows it casts make it appear most
prominent. |
