African/Arabian: A more northerly detailed view of the
African/Arabian/Eurasian plate boundary, from the Sea of Galilee to
the Gulf of Iskenderun. Fine shot of the jog in the Dead Sea zone.
The orientation of the boundary changes from north to northeast
within Lebanon and Syria, where the Arabian and African blocks begin
to interact with the Eurasian plate and the Zagros Mountains have
been uplifted.

Arabian Peninsula: Across the Arabian Peninsula from the Red
Sea is the Dead Sea fault zone, another region of rifting as well as
strike-slip faulting. This view places the Dead Sea zone in the
grander context of interactions among the African plate (Arabian
Peninsula, Israel, Lebanon), the Arabian plate (Saudi Arabia, Syria),
and the Eurasian plate (Turkey, Gulf of Iskenderun in upper part of
photo). The African-Arabian plate boundary, like most plate
boundaries, is irregular with steps, jogs and differing styles of
deformation. The blocks flanking the long straight faults of the Dead
Sea zone are moving laterally past each other, as well as rifting
apart.

New Mexico: Excellent photograph of the whole New Mexico
portion of the Rio Grande rift in its larger context. The green band
snaking down the center of the view is the Rio Grande. From the
Franklins near El Paso, northward through Colorado, the mountain
ranges flanking the rift valley trend north. The valleys are commonly
asymmetrical (half-grabens) -- deeper on the side closest to the
range front. Along the length of the rift, the ranges are separated
from each other by transfer fault zones that generally trend
northeast in this region.

New Mexico: One of a very few photos of the Rio Grande rift
showing the interaction between faults of the rift valley, which head
northward from El Paso, and faults of the Border Corridor transform
zone, which head southeastward to Big Bend National Park. The
Franklin Mountains, within El Paso, trend north and are typical of
the rift ranges throughout New Mexico and into Colorado. Sierra
Samalayuca (SE of Sierra Juarez near El Paso) trends southeast, as do
most ranges within the transform zone. Volcanoes commonly mark such
corners where major rift structures change trend; the Potrillo
Mountains (dark area west of El Paso) are volcanic peaks in that
setting.
