A Few Photos from the Archives

Thistle Landslide in Spanish Fork Canyon, Utah in the spring of 2000.

Light green Jurassic Curtis Formation atop the brown stripes of the Summerville Formation on the San Rafael Swell, Utah

Light greenish gray beds of the Tertiary Green River Formation overlying red beds of the Wasatch Formation in southwestern Wyoming.

Scenic San Rafael Swell, Utah.

Spring flowers on the San Rafael Swell, Utah.

Light green beds of the Cretaceous Cedar Mountain Formation above the purples and reds of the Jurassic Morrison Formation near the Dalton Wells dinosaur quarry north of Moab, Utah.

Red blossoms bloom on a cactus in springtime on the San Rafael Swell, Utah.

In this photo, the brick red Triassic Moenkopi Formation is at the base of the cliff. It is overlain by a greenish and purplish slope of the Triassic Chinle Formation (with the prominent Black Ledge Member near the top of this formation). At the top of the cliff is the massive sandstone cliff of the Triassic (and perhaps partly Jurassic) Wingate Sandstone.

Rock art in the Tertiary Green River Formation of Wyoming. This circular feature is call a concretion.

Sandstones and coal beds of the Cretaceous Blackhawk Formation just west of Helper, Utah.

Vineyards stretch across the Sonoma Valley, California in the spring of 2000.

Photos from a trip to Eocene mammal fossil localities in Wyoming and Utah. Click on the photos to see a larger view. You can read about the trip at http://urthreport.blogspot.com/

Halfway Hollow in the Duchesne River Formation south of Utah Hwy 121. This locality has produced quite a number of micro-mammal bones and teeth. Many of these fossils are only a millimeter or two in size.

Stuck again, this time in the sand.

Sandstone hoodoo in Uinta Formation, Utah.

Along the White River south of Bonanza, Utah. The low light colored outcrops near the river on the right are the Green River Formation. All the rest of the outcrops are of the Uinta Formation. The Green River and Uinta Formations were deposited in lakes about 45-50 million years ago and contain a good fossil record of the animals and plants that lived in and around these lakes.

Van stuck in swelling clays of the Bridger Formation, Wyoming. Be careful where you drive when it's wet!

The Bridger Formation at Grizzly Buttes, southeast of Mountain View, Wyoming. The dark stripe near the bottom of the hills is the Henry's Fork Tuff bed that has an age of 46.9 million years. Thousands of fossil mammal bones and teeth have come from this area.

The Bridger Formation at Jackson Ridge along the Oregon/Mormon Trail in Wyoming. Site of numerous Eocene mammal fossil discoveries in the late 1800's. The fossils are about 48 million years old.

The Bridger Formation at Church Butte, Wyoming along the Oregon/Mormon Trail. Site of Eocene mammal fossil discoveries in the late 1800's.
