About CLPX Snow Pit Data

Investigators for the Cold Land Processes Field Experiment (CLPX) dug and took measurements from approximately 2,000 snow pits as part of the CLPX project. The majority of the snow pit data were collected within the Intensive Study Areas (ISAs) inside each Meso-cell Study Area (MSA), during the four Intensive Observation Periods (IOPs). In addition, snow pit data were collected across the North Park MSA and in several other areas as part of other field collection efforts.

Although different investigators collected snow pit data for different purposes and in different locations, they all followed the same data sampling protocol and all snow pit data are presented in the same format. See the CLPX Snow Pit Measurements documentation for details of the sampling protocol and data format.

The following links correspond to interactive maps which display snow pit locations within each regional CLPX study area. Each map contains links to additional detail of each study area. Refer to the CLPX Snow Pit Map Legend in Table 1 for information regarding snow pit type, location, and description, as well as links to select data and documentation.
