The Surficial geology section is divided into Alluvial landforms & processes, Glacial history & landforms, Glacial rebound & coastal landforms, and Mass wasting. Explore those sub-categories or find general information below. You can also view the entire JuneauNature hierarchy at this site map.
Surficial geology is the study of loose, unconsolidated material overlying the bedrock foundation. These layers were deposited, rearranged and eroded by glaciers, fluctuating sea level, streams, landslides, and bulldozers. While bedrock geologists tend to think in time-frames of millions of years, the surficial story is usually faster paced, taking place over millennia and mere centuries.
