Macun 1 Rock Glacier Movement Survey 1965-1997

Swiss Alps data documents the Macun 1 rock glacier in the Lower Engadine, Grisons. Measurements from 1965 to 1997 by Dietrich Barsch and co-operators track horizontal displacement and surface elevation changes. The dataset was originally published on the CAPS Version 1.0 CD-ROM in June 1998.

Use Cases

• Analyzing long-term horizontal displacement rates using survey data from 1965-1997.
• Investigating acceleration in glacier movement post-1988 as noted in source descriptions.
• Correlating surface elevation changes (2720 m to 2610 m asl) with climatic variables.
• Establishing baseline movement data for future triennial survey comparisons.

Strengths

• Provides a 32-year continuous measurement record from 1965 to 1997.
• Data originates from systematic field surveys by a recognized investigator (Dietrich Barsch).
• Captures a notable acceleration in horizontal displacement after 1988, a key temporal signal.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source.
• Conflicting last updated dates exist: 1997-12 31 on NASA Earthdata versus 2026-03-12 on Data.gov, suggesting metadata inconsistency.
• Original data format (BIN, ISO) may require specialized tools for access.
