Tree rings tell a tale of rainfall and drought

(Sheridan, Wyo.) — Sure, we all know tree rings tell a story. But do we understand why? The Council for the Bighorn Range, SWACA Environmental Consultants and Little Bighorn Trout Unlimited are sponsoring a talk with Bryan Swindell, GIS Scientist, on a study pertinent to the history of climate in the Bighorn Mountains called "Trees as Prehistoric Streamflow Gauges: 800 Years of Water Supply Data for the Bighorn Mountain Region" by – Bryan Swindell of SWCA Environmental Consultants. The talk is Thursday at 7 p.m. at the Sheridan County Fulmer Library. During his presentation, Swindell will review a comprehensive set of streamflow reconstructions for several modern-day USGS gages in the Bighorn Mountains region, reaching as far back as AD 1200. The reconstructions paint a highly variable picture of streamflow, with many droughts and pluvials that exceed those witnessed during the last 100 years in both duration and magnitude. During the presentation, Swindell will discuss the science of tree-ring research, the results of his work, and the implications for water supply and natural resource management in the Bighorn region. Bryan Swindell has called the Northern Rockies home for the last 15 years, living in Idaho, Montana and now Sheridan. Bryan works for SWCA Environmental Consultants as a geographic information scientist, supporting projects related to water resources, climatology, fish and wildlife, archaeology, and land-use planning. Bryan worked with the USGS Rocky Mountain Science Center in Bozeman to complete this research while earning his Master's degree in Earth Sciences from Montana State University.
