  • Portion of Echo Park Closed Due to Mountain Lion Activity

    The closed area includes the group campsite (other campsites remain open), river access area, the adjacent restroom, water spigot and the path following the Green River upstream to its confluence with the Yampa River. A fresh animal kill is in the area.

Why are we photographing the quarry wall fossils and documenting the current conditions of the bones?

By photographing each bone on the wall, we will have a digital visual record of its state in 2012, which can then easily be used for future comparison to see if cracks have expanded or have finally been stabilized. Each bone will be photographed and the condition of cracks and repairs on the bone recorded. Digital technology makes the monitoring project much simpler and easier than using old paper record methods.

 
Cracked Bones
Here you can see a large crack passing through not only a dinosaur bone, but also the surrounding rock itself.  This crack has not been repaired, and will be monitored closely to see if conditions worsen over time or have stabilized themselves.

Picture of mormon cricket perched on a blade of grass.

Mormon crickets are wingless grasshoppers that swarm across roads through the summer in the western United States. These flightless insects can form such large swarms that the road appears to move and change colors where they cross.
