In the fall of 1991, I had the pleasure of going with the University of
Paris on a field trip to the French Alps. We dug up fossils and
observed lots of sedimentary rock formations.
01 - These were the students and the professors
from the program.
02 - Me in front of the Vélodrome - a
nickname based on the fact that the curved rocks look like a bicycle
racing track.
03 - This is a species of evergreen which changes
color and loses its needles in the fall.
04 - We were looking for rocks and fossils, but
often got some extra surprises.
05 - Usually anticlines (layers of rock bent in
an "A" shape) are difficult to see because they are hidden
under other rocks or vegetation. This one has been beautifully
exposed to show its shape.
06 - The layers you can see are called
strata. You can get an idea of how big they are by the young
man standing in the left of the photo.
07 - Here's another anticline, but this one has
been pushed over on its side.
08 - The vegetation on each side of this valley
is noticeably different. Can you guess why?
09 - This is a fossil of an organism which lived
about 175 million years ago. It's called an ammonite.
