Fig. 2. Comparison of a section of Missouri River near Atchison, Kansas, as it 

 was mapped in 1890 and in 1945, showing narrowing and regularization of the 

 channel by training dikes and bank revetment. Downstream migration of Rush- 

 ville Bend, and location of an 1891 cutoff which isolated the former river port 

 of Doniphan, are also shown. The 1946 bank line was mapped late in 1945.
