DESCRIPTION:Over 100 year ago\, Professor James Church started measuring t
 he snowpack in the Mount Rose/Lake Tahoe (California/Nevada United States)
  area for snowmelt runoff estimation. Across the western US\, this prompte
 d the implementation of the snowcourse data that comprised monthly snowpac
 k measurements at up to 2000 locations. In the late 1970s\, this network w
 as supplemented by the automated snow telemetry (SNOTEL) network that now 
 has over 800 stations measuring snow and related variables on a daily or e
 ven hourly basis. These two network provide a wealth of information\, but 
 have a variety of limitations too. What happens in areas where we do not h
 ave many measurements? Snow depth is a simple variable to measure\, but ho
 w representative are the measurements? Operational data are used with fiel
 d data to illustrate how we need to sample the snowpack\, especially to co
 nsider scales of sampling and how representative measurements are. Remotel
 y sensed data are presented that can integrate field and point measurement
 s to larger areas while expanding the period of record or sampling interva
