I want to know the answer to the following question:
The idea of an ice-age that completely covered a continent was suggested by whom?
All the background I'm provided with is that "Louis Agassiz and others established the reality of continent-covering ice ages, and "fluvialists" like Andrew Crombie Ramsay argued that river valleys were formed, over millions of years by the rivers that flow through them.". Is that enough to answer the question?
Answer: yes
