Tunisia in 1976

In the spring of 1976, I worked as a field assistant and interpreter (most of the people spoke some French) for Dr. J. Keith Rigby, Sr. in Tunisia. Keith was studying Permian biohermal reefs that outcropped in the mountains near the city of Medenine, but we had the opportunity to travel to a number of places in the country. The scenery was spectacular and the people were warm and friendly, always wanting to stop and visit with the odd Americans tromping around in the desert.

The village of Chenini built into the side of the hill.

Here I am with a group of children. They seemed to pop up out of nowhere. I could usually find a coin or piece of candy for them.

Taking the ferry across the Mediterranean to the Isle of Djerba, a popular tourist stop with spectacular white sand beaches.

A handsome young Tunisian boy; one of my many young friends while in the field. He is standing behind a block of sandstone that has Triassic vertebrate tracks all over it.

The open market in Medenine where you could find almost anything for sale.

A young mother at her home in Matmata, Tunisia, a town cut out of the loess deposits where the homes are carved down into the earth. After carving out a home in the loess, they would typically whitewash the walls.

The town of Metameur, Tunisia.

Baskets of olives curing on a rooftop in the Djebel Tebaga hills west of Medenine, Tunisia.

Roman temple ruins at Gightes, Tunisia. While in the hills west of Medenine, we found old Roman quarries with marble columns partially formed, but still in the rock like the one seen below.

The hills of Djebel Tebaga where we conducted our studies. The massive rock in the middle of this photo is a small fossil reef, called a bioherm, made up mostly of fossilized sponges. I am standing on a layer of sandstone that laps up onto the fossil reef.

Me climbing out of our field vehicle. The little Renaut got us around very well on the less than ideal roads of the Tunisian countryside.

Photo of me on the outcrop in the Djebel Tebaga, wearing my Camp Loll, BSA T-shirt and probably pretending to know what I was looking at.

My mentor and friend, Keith Rigby, not in Tunisia, but sitting on the lawn at a home in Gunlock, Utah where we were running the BYU field camp one season.

California 1983

On a geology field trip in April 1983 led by Dr. Myron G. Best and myself I dug out these old pictures. Some of the old 35 mm slides are still pretty nice.

 Green hills of the Coast Range looking out over the San Jose valley.

 Tiburon Peninsula on a rainy April day with the occasional blueschist or greywacke knocker poking up through the grass.

Early morning along the Merced River gorge outside of Yosemite.

Agmatite – a mass of rock thought to represent the collapsed roof of a magma chamber.

 Bridal Veil Falls in Yosemite Valley in the morning light.

Another example of agamite with numerous inclusions of different types in the granite matrix. Located along the Merced River gorge near Yosemite National Park.

Landslide on road west of Yosemite. The spring of 1983 was one of the wettest the west had seen in over 100 years causing many landslides.

The beautiful U-shaped, glaciated Yosemite valley.


Flow layering and folding in the rhyolite lava flows near Mono Lake, California near Mammoth, California.

More of the flow folded rhyolite lava. Just spectacular.
