as much water and lasted about 70 percent as 

 long after disappearance of undrifted snow as 

 the drifts formed back of clumps of fir trees. 



In 1957, Meeuwig continued and extended 

 the study of inducing snowdrifts. A drift in- 

 duced by a 16-foot snow fence was 15 feet 

 deep and contained 100 cubic feet of water 

 per lineal foot of fence whereas adjacent un- 

 drifted snow was only 8 feet deep. The in- 

 duced drift persisted 10 days later into the 



summer than the undrifted snow, and average 

 water content along the main axis of this drift 

 was 13 inches. Meeuwig's results were promis- 

 ing, but shifts in personnel and program em- 

 phasis prevented any further work on snow 

 drifting at the Great Basin Station. The 

 Rocky Mountain Forest and Range Experi- 

 ment Station has subsequently done consider- 

 able additional research on induced snow 

 drifting.
