Designated Site #3 in park literature, the Denio Site is
located on the east side of the park, below the camping
area. The Denio Site is one of the
most interesting track areas in the park, containing several types of
tracks and a number of unusual track features. However, because
there is no easy access point or parking area nearby, is usually
under shallow water, it is seldom seen and little appreciated by
most park visitors. Most of the site has been mapped, and some
molds have been taken. This is fortunate, since several tracks
have been lost to the cracked and disintegrating track bed
here, and others are in danger of being lost in the near future.
Among the interesting features on this site are the following:
1. Several trails of distinct theropod tracks, including some
that intersect.
2. A long-striding theropod trail with erratic paces and track angles.
3. Two trails with mud-collapsed metatarsal tracks, possibly
responsible for some early claims of "moccasin" prints.
4. A sauropod trail, evidently heading north (opposite most in the park).
5. A long foot slide.
6. Two possible tail marks.
7. Many isolated toe marks and faint or incomplete tracks.
8. A very long trough of unknown origin.
