Group: Summary

   This data set includes the results of laboratory experiments examining the 
   constitutive properties of subglacial till, under dynamic stressing. The data 
   include the results of shear strain and stress experiments. Testing was 
   carried out in a servo-controlled biaxial shear device under controlled 
   temperature and stress conditions, allowing both sliding and microstructural 
   processes to be studied in detail. Till samples were collected from Matanuska, 
   Alaska and from Caesar till at the Laurentide Ice Sheet. 

   The data are available via FTP in ASCII text format (.txt).
