Lake Powell has been called one of the most
 
beautiful lakes in the world. Fodor's "Nights to
 
Imagine" lists it among their 32 most unusual and
 
unexpected places to spend the night in the United
 
States, describing it as a vast streach of tectonic
 
dream-scape.
 
 
     Paleontologists have called it the Jurassic Park of
 
southern Utah and northern Arizona.
 
 
     Surrounding the pristine clear waters of Lake
 
Powell, rock formations deposited during the time of
 
dinosaurs contain their tracks and traces. This book
 
presents a glimpse of the remnants of that time
 
passed.
 
 
     Imagine a creature walking along a beach,
 
and it wasn't yesterday or last week or a month ago...
 
It was 200 million years ago.
 
 
     Then imagine finding remnants of that beach, now
 
turned to stone, eroding out of a cliff. When you
 
examine it, you see the tracks of that beach-walker
 
from so long ago.
 
 
     Then you realize that you may be the first person
 
ever to see these traces and recognize them for what
 
they really are.

     There is something wondrous the first time you
visit a natural history museum and witness the skeletons of dinosaurs towering over you, the hundreds of millions-of-years old bones, a testament to an unfamilar world that came before.

Then the questions arise: How did they live? What did they eat? How did they move?

     The bones tell part of the story, but the discovery of dinosaur tracks refine and illuminate our understanding of their behavoir, the ways in which they walked, socialized, and interacted within their environment.

     Over the course of the last 12 years  Andre Delgalvis, a professional photographer and naturalist, has discovered and documented hundreds of track sites  during his exploration of Lake Powell in the Glen Canyon National Recreation Area in southern Utah and northern Arizona. His photographs and instructional text are gathered in his book "The Lost Tracks: A Journey of Discovery".
 
     These discoveries not only contribute to the scientific understanding of these prehistoric creatures, but they also illustrate what is possible by being observent in your own surroundings.
