Where did J Harlen Bretz live?

Homewood, Illinois
Bretz met his wife Fanny Chalis at college – she was also studying biology – and they married in 1906. They had two children: Rudolf and Rhoda. J Harlen Bretz died, age 98, on February 3, 1981, at home in Homewood, Illinois. He was survived by his son and daughter.

What theory did J Harlen Bretz?

flood theory
Bretz introduced his flood theory in a paper published in late 1923. He included a detailed geomorphic map of what he called “the Channeled Scabland,” showing a network of branching and interconnecting channels that he concluded could only have been carved by a fast and furious inundation.

Who discovered the Missoula Floods?

Geologist J Harlen Bretz
Geologist J Harlen Bretz first recognized evidence of the catastrophic floods, which he called the Spokane floods, in the 1920s.

What was the source of the water that carved out the Scablands?

The collapse of the ice dam released a sea of water. This water then traveled at up to 60 miles per hour, rushing headlong towards the Scablands. It took only a few hours for the waters to reach this once flat landscape. In places the water was a staggering 800 feet deep.

Was Missoula a lake?

Lake Missoula was a prehistoric proglacial lake in western Montana that existed periodically at the end of the last ice age between 15,000 and 13,000 years ago.

What was Harlen Bretz’s theory about how these formations were made?

Bretz first presented his ideas at the 1923 annual meeting of the Geological Society of America, where he hypothesized that the scablands were formed from glacial erosion and flowing water from glacial ice (Alt, 2001).

How far south did the Missoula flood go?

The flood path traveled west through much of the Columbia River Gorge covering 16,000 square miles (Kartevold & Stanley, 2001). Some of the floodwater diverted at the Willamette Valley reaching as far south as Eugene, the rest of it continued west pouring out into the Pacific Ocean.

How many times did the Missoula Floods occur?

What a great question – I wish I had a great answer. The Missoula Floods actually happened many times (possibly as many as 30 times!) near the end of the last ice age.

What did J Harlen Bretz think caused the strange features in the Scablands?

But during the 1920s a geologist named J Harlen Bretz outlined a startling hypothesis. His fieldwork convinced him that the scablands were not the result of slow geological weathering, but of an enormous catastrophe that had taken place almost overnight when a titanic flood engulfed the region.

How many coulees are in Washington state?

About 150 distinct coulees have been identified; some of them are hundreds of feet deep. The two largest are Moses Coulee, which is 40 miles long, and Grand Coulee, which is 60 miles long.

Why did Lake Missoula flood?

At the end of the last Ice Age, 18,000 to 15,000 years ago, an ice dam in northern Idaho created Glacial Lake Missoula stretching 3,000 square miles around Missoula, Montana. The dam burst and released flood waters across Washington, down the Columbia River into Oregon before reaching the Pacific Ocean.

How was Lake Missoula created?

Glacial Lake Missoula formed as the Cordilleran Ice Sheet dammed the Clark Fork River just as it entered Idaho. The rising water behind the glacial dam weakened it until water burst through in a catastrophic flood that raced across Idaho, Oregon, and Washington toward the Pacific Ocean.

Who was Harley Bretz?

Harley Bretz was born on September 2, 1882 in Saranac, Michigan, USA. His parents were farmers: Oliver Joseph Bretz and Rhoda Maria Howlett. His father also ran a furniture store and undertakers business. Harley was the eldest of their five children. In later life, as a joke, he changed his name to J Harlen Bretz.

Where was Harland J Bretz born?

The county birth registrar recorded his name as “Harlan J. Bretz” when he was born, on September 2, 1882, in the small town of Saranac, in central Michigan’s Ionia County. He was listed as “Harland J. Bretz” in the 1900 Census.

What happened to Harlen Bretz?

J Harlen Bretz died, age 98, on February 3, 1981, at home in Homewood, Illinois. He was survived by his son and daughter. His wife Fanny died in 1972. Bretz donated his body to science, so there was no interment.

Who is Harlen Brett?

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.
