Summary

This dataset includes processed tree ring data from avalanche paths in southeast Alaska, USA. The data were processed in three distinct phases that resulted in this dataset: collection, processing, and avalanche signal analysis. This dataset consists of samples from 434 cross sections from 426 unique trees throughout six avalanche paths in the study region. This resulted in 2706 identified growth disturbances (GDs) due to avalanches.

Purpose

These data were collected as part of the USGS Snow and Avalanche Project of the U.S. Geological Survey Ecosystems Mission Area Climate Research and Development Program and the USGS Alaska Climate Adapatation Science Center. Understanding avalanche processes and associated large magnitude avalanche return intervals is critical for local and regional avalanche forecasting operations, transportation agencies, and planners. These data can be used to examine large magnitude avalanche patterns on both temporal and spatial scales. This dataset ultimately serves to enhance public and worker safety, and understand landscape disturbance processes and change in mountain ecosystems.
