3. Chicago was a big change for a 10 year old.
It was fun to show my new friends their city.
4. Augustana College - Swedish Lutheran heritage and the discovery
that geology could be a career choice. It was also on campus where
I fell in love with Carol Jayne Anderson.
Class of 1956
5. My field course was in the Black Hills, SD. Here we learned to map the
formations and volcanic features in the NE part of the uplift.
Carol and I were married after
conclusion of the field course.
6. The old capitol at the University of Iowa where graduate work was
completed in 1961. First born son David born in Iowa City.
8. Geology summer jobs during my student days
provided rich experiences.
Serviced groundwater level recorders and
measured discharge from springs while
working for the U.S. Geological Survey in
Kentucky.
Explored for potential iron ore in Michigan’s
Upper Peninsula for Cleveland- Cliffs.
Studied stratigraphy in the
Big Snowy Range of central
Montana for Shell Oil Co.
9. Exploring the gulf coast for petroleum with the
California Company (Chevron) in New Orleans and
Lafayette.
10. Assistant professor at Monmouth College from 1962-1968
Daughter Kirsten was born in Monmouth - 1964.
11. Two National Science Foundation Summer Programs enriched my
field experience and my specimen collection for teaching students
in the classroom. One was a circum-Lake Superior tour with leaders
from Michigan Tech at Houghton. The other featured a study of
volcanic rocks in the Yellowstone region. An excursion that gave us
permission to collect from within the park.
Hotspot volcanism commenced ~17 Ma in
northeastern Nevada and continues to the
present
The rocks of Lake Superior's North Shore date back
to the early history of the earth. During the
Precambrian (between 4.5-billion and 540-million
years ago) magma forcing its way to the surface
created the intrusive granites of the Canadian Shield.
These ancient granites can be seen on the North
Shore today. It was during the Penokean orogeny, part
of the process that created the Great Lakes Tectonic
Zone, that many valuable metals were deposited. The
region surrounding the lake has proved to be rich in
minerals.
12. Spring field trips to Colorado included students from
Monmouth, Knox and Lawrence Colleges.
Canyon City embayment Garden of the Gods,
Colorado Springs
13. Taught in the Boundary Waters Wilderness in a program of the
Associated Colleges of the Midwest.
15. Introductory geology classes visited Kettle Moraine State Park to
learn about kettles, drumlins, eskers and other glacial features.
The red line shows
the limit of glacial
advance.
16. Field trip locales in Wisconsin and Upper Michigan
The Baraboo Hills, which form an elongated, discontinuous ring in Sauk and Columbia
Counties, rise approximately 700 feet above the surrounding landscape. They are composed
of near-shore ocean sediment, deposited about 1.7 billion years ago, which has been
metamorphosed, folded, and lifted up. This rock, called quartzite, is distinctively red,
extremely hard, and resistant to erosion. During the maximum extent of the most recent
glaciation, approximately 20,000 years ago, the Green Bay Lobe of the Laurentide Ice Sheet
surrounded the eastern half of the hills. It deposited moraines that block each end of an
ancient valley that now contains Devils Lake. Today, the Baraboo Hills are one of the largest
forested areas in southern Wisconsin and home to Devils Lake State Park.
17. Field trips to the Marquette Range and the Menominee Range were
conducted in support of structural geology and petrology classes.

18. The Keweenaw peninsula (‘copper country’) is another beautiful area
with abundant examples of sedimentary and volcanic rocks along with
interesting structural geology features.
19. Colorado raft trip on the centennial anniversary of John Wesley
Powell’s first trips (1869-1872)
20. Received grant to establish Introductory Geology in the Rock Mountains
for the Associated Colleges of the Midwest. We chose Montana State
University for our base.

21. Research with professors from Montana State University and the
University of Idaho led to a book on the geology of the northwest
portion of the Beartooth Mountains (Livingston corner).
22. Two summers were at the Indiana University Field Station
We lived in a nice trailer home and the family really enjoyed the experience.
Horses ranged around the site and a trout stream ran through it.
23. The location of the field station in the Tobacco Root Mountains
gives access to a wealth of geologic features in western Montana.
24. A series of images reflecting our year of homelessness. We traveled in a Dodge ‘pop
top’ van with our three kids and a dog. Subtitle “Travels with Tippy’ (apologies to John
Steinbeck. It was 1974-1975 and all the National Parks and Monuments were prepared
for the celebration of our nation’s bicentennial.
First stop was
at the
Indiana
University
Field Station
36. During the late ‘70s and early ‘80s I was involved in gas exploration,
mostly in Pennsylvania and the southern tier of New York.
The Pennsylvanian oil rush was
an oil boom that started in
Titusville, Pennsylvania in 1859,
as Edwin L. Drake struck "rock
oil". I was thrilled to be able to
visit this site where the oil
industry began.
37. One project was as far away as the Nirihuau Basin in Argentina.
38. Return to the Bighorns – taught 12 summer field camps for the
University of Illinois.
Near Eaton’s Ranch
Piney Creek thrust
Sheep Mountain anticline
39. Field camps always included a ‘Parks Trip’ to Yellowstone and
other Wyoming mountain locales.
40. The Tetons were a scenic and geologic highlight of the field course.
Over these seemingly
changeless mountains, in
endless succession, move
the ephemeral colors of
dawn and sunset and of
noon and night, the
shadows and sunlight,
the garlands of clouds
with which storms adorn
the peaks, the misty rain-
curtains of afternoon
showers.
—Fritiof Fryxell, The
Tetons: Interpretations of
a Mountain Landscape
42. Heart Mountain is an 8,123-foot klippe just north of Cody in Wyoming, sticking up from
the floor of the Bighorn Basin. The mountain is composed of limestone and dolomite of
Ordovician through Mississippian age (about 500 to 350 million years old), but it rests on
the Willwood formation, rocks that are only about 55 million years old—rock on the
summit of Heart Mountain is thus almost 300 million years older than the rocks at the
base. For over one hundred years geologists have tried to understand how these older
rocks came to rest on much younger strata.
43. I taught a field course at Arizona State University, Flagstaff
San Francisco Peaks – a stratovolcano
44. Crater atop the cinder cone at
Sunset Crater Volcano National Monument
45. Also taught with the
University of Arizona field
course in southeast Arizona

46. Lawrence field trip to Las Vegas
Valley of Fire State Park
Death Valley
Grand Canyon -Bright Angel Trail
47. Lawrence field trip to Big Bend National Park
Big Bend National Park, located along the Rio Grande at the United States
border with Mexico, is situated in the Chihuahuan Desert. The fragile desert
ecosystem displays enormous beauty, includes mountain and basin
environments, hosts an extraordinary diversity of native plants and animals,
and is the site of significant mineral deposits and historic mercury mines.
48. Big Bend is part of the Marathon orogenic belt and subduction zone formed from
collision between the North and South American plates.
49. We stayed at Holden Village for parts of two summers.
Originally the village was built in support of the Holden Mine. Now it is operated
by the Lutheran Church as ‘A Place Apart.’
Arriving is done by ferry and bus up the
old narrow gauge railroad route.
Waste rock from the mine
is visible in the foreground.
