Fossil Plants & Insects of the Green River Formation,
Parachute Creek Member



The Western Interior Paleontological Society (WIPS) conducted another trip to Douglas Pass, Colorado for fossil plants and insects in the Eocene Upper Parachute Member of the Green River Formation.  The fossils shown here were found during the WIPS trip from 6/30/04 to 7/4/2003 (and beyond).  The primary dig was conducted under a permit from the Bureau of Land Management (BLM), Grand Junction Office.  This field trip is an annual event conducted by WIPS members Michael Graham & Bill Bateman.  All rare specimens are placed in the permanent repository at the Denver Museum of Nature & Science (DMNS). 

DMNS recently released on online identification database for fossil plants of the Green River Formation, Parachute Creek Member on their website at:

Fires are an ever-present threat in western Colorado.
One such fire exploded just over the ridge from our campsite.
A call to 911, with a transfer to the BLM fire squad led 
to slurry bombers and smoke jumpers within 35 minutes.

Note: Anyone visiting Douglas Pass should be aware that the main Radar Dome excavation site is off limits due to an environmental impact study being conducted by BLM.  There are several issues contributing to the closure of this site: (1) damage/erosion; (2) emitted radiation from the dome; and (3) security of the dome.  For updates on the status of this site, contact the BLM, Grand Junction office.

If you find any errors in identification, please contact Steve Wagner.
