It must be noted here that there are extensive "loessless" regions 

 in the southeastern as well as in the northeastern corners and else- 

 where in the state. Frozen sand blocks have been observed in the 

 drift of Iowa as well as in Nebraska, but as far as can be learned 

 no examples yet found equal those in the Milford cut-off in point 

 of size, variety, or numbers.
