J Harlen Bretz
J Harlen Bretz (September 2, 1882 – February 3, 1981) was an American geologist, best known for his research that led to the acceptance of the Missoula Floods and for his work on caves. He was born to Oliver Joseph Bretz and Rhoda Maria Howlett, farmers in Saranac, Michigan, the oldest of five children. He earned a degree in biology from Albion College in 1905, where he also met his wife Fanny Chalis. Thereafter, he became interested in the geology of Eastern Washington state.

Bretz was of German heritage. Bretz graduated with his AB from Albion College in 1905. He then started his career as a high school History and Physiography (study of the physical features of the Earth's surface) teacher in Seattle. During this time he began studying the glacial geology of the Puget Sound area. He continued his studies at the University of Chicago where he earned his Ph.D. in geology in 1913. He became an assistant professor of geology, first at the University of Washington and then the University of Chicago.
He made important discoveries regarding the origin of the Channeled Scablands.
The Spokane floods: an outrageous hypothesisEdit
Since 1910 he had been interested in unusual erosion features in the area after seeing a newly published topographic map of the Potholes Cataract. Bretz coined the term Channeled Scablands in 1923 to describe the area near the Grand Coulee, where massive erosion had cut through basalt deposits. The area was a desert, but Bretz's theories required cataclysmic water flows to form the landscape, for which Bretz coined the term Spokane Floods in a 1925 publication.
Bretz published a paper in 1923, arguing that the channeled scablands in Eastern Washington were caused by massive flooding in the distant past. This was seen as arguing for a catastrophic explanation of the geology, against the prevailing view of uniformitarianism, and Bretz's views were initially discredited. However, as the nature of the Ice Age was better understood, Bretz's original research was vindicated, and by the 1950s his conclusions were also vindicated.
Bretz encountered resistance to his theories from the geology establishment of the day. The geology establishment was resistant to such a sweeping theory for the origin of a broad landscape for a variety of reasons, including lack of familiarity with the remote areas of the interior Pacific Northwest where the research was based, and the lack of status and reputation of Bretz in the eyes of the largely Ivy League-based geology elites. Furthermore, his theory implied the potential possibilities of a Biblical flood, which the scientific community strongly rejected. The Geological Society of Washington, D.C invited the young Bretz to present his previously published research at a 12 January 1927 meeting where several other geologists presented competing theories. Bretz saw this as an ambush, and referred to the group as six "challenging elders". Their intention was to defeat him in a public debate, and thereby end the challenge his theories posed to their conservative interpretation of uniformitarianism.
Another geologist at the meeting, J.T. Pardee, had worked with Bretz and had evidence of an ancient glacial lake that lent credence to Bretz's theories. Pardee, however, lacked the academic freedom of Bretz (he worked for the US Geological Survey) and did not enter the fray.
Bretz defended his theories, kicking off an acrimonious 40 year debate over the origin of the Scablands. As he wrote in 1928, "Ideas without precedent are generally looked upon with disfavor and men are shocked if their conceptions of an orderly world are challenged."
Both Pardee and Bretz continued their research over the next 30 years, collecting and analyzing evidence that eventually identified Lake Missoula as the source of the Spokane Floods and creator of the Channeled Scablands. Research on open channel hydraulics and NASA satellite images in the 1970s further vindicated Bretz's and Pardee's theories.
Caves and karstEdit
Bretz wrote an extremely influential paper on the morphology and origin of limestone caves (1942) together with detailed studies of the caves of Missouri (1956) and Illinois (with Stanley Harris, 1961).
Awards and honoursEdit
The National Speleological Society made Bretz an honorary member in 1954.
Bretz received the Penrose Medal; the Geological Society of America's highest award, in 1979, at the age of 96. After this award, he told his son: "All my enemies are dead, so I have no one to gloat over."
Each year at Albion College, the J Harlen Bretz Award is given to the most outstanding senior in the geology department.
Bretz Drive in Homewood, Illinois was named in his honor.
A plaque was dedicated to Bretz in 1994 outside the Visitor Center at Dry Falls State Park in Coulee City, Washington that reads "Dedicated to J Harlen Bretz who patiently taught us that catastrophic floods may sometimes play a role in nature's unfolding drama"
Bretz and his wife Fanny had two children, Rudolf Challis Bretz and Rhoda Bretz Riley. The Bretz family settled in Homewood, Illinois where they bought property and constructed a Sears Catalog Home on it in 1921. Bretz nicknamed the property "Boulderstrewn" because of all the rocks and minerals he collected and was given that were placed around the property. He donated a portion of this collection to Albion College in the 1970s . Boulderstrewn was renowned for being an active place where Bretz hosted many parties with students and faculty from the University of Chicago. His post-retirement body of work includes Geology of the Chicago Region (1955), The Caves of Missouri (1956), Washington's Channeled Scabland (1959), Caves of Illinois (1961), and Geomorphic History of the Ozarks (1965) -- in addition to his 1949 Incomplete Genealogy of the Family of John Bretz Of Fairfield Co., Ohio, with a Partial History of One Line of Descent in this Family.

Reputedly he was born Harley Bretz, in Michigan...
- Bretz's daughter explains how he got his name. "He invented the Harlen thing, just as he had invented the J in front of his name--made the whole thing up. 'Harley Bretz' was his given name, but it just didn't ring a bell for him; maybe he didn't think it sounded professional enough." Says Bretz's daughter Rhoda Bretz Riley in the book Bretz's Flood page 12. Bretz's Flood, by John Soennichsen, published by Sasquatch Books Seattle, Copyright 2008 .
