BLIZZARD, SAN DIEGO COUNTY. 
On a high point near the center of Sand Hills, about 8 miles a little 
south of west from Ogilby, a station on Southern Pacific Railroad 10 
miles west of Yuma. It is impossible to describe this point very accu- 
rately, as the hills arc very similar and change more or less with every 
sand storm. 
Signal: A lumber tripod. 
Station mark: A 2 by 3 stake set in sand under center of tripod. 
No bench mark was available when station was occupied, and it is 
impossible to preserve this point.
