Tree Ring Chronology from Lake Minotaur High in Washington

Tree ring data from the NOAA/WDS Paleoclimatology archive provides a 142-year chronology from 100 to -42 calendar years before present. This record, part of the International Tree-Ring Data Bank (ITRDB) as series WA115, was collected from Abies lasiocarpa (ABLA) trees near Lake Minotaur High in Washington, USA. The dataset was archived by the NOAA National Centers for Environmental Information in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width series.
• Calibrate climate models for the Pacific Northwest using the precisely dated 142-year chronology.
• Study the growth response of subalpine fir (Abies lasiocarpa) to historical environmental stressors.
• Cross-date and validate other tree-ring chronologies from the Washington region using the ITRDB WA115 series.

Strengths

• Covers a 142-year time period (100 to -42 BP) from a single geographic location.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.

Limitations

• Temporal coverage is relatively short for paleoclimate studies at 142 years.
• Data is geographically limited to a single site (Lake Minotaur High, Washington).
• The dataset is temporally stale, with no updates since its archival in 1992.
