The bay has changed substantially since then, in large part due to the swiftly receding Shoup Glacier, which has lost roughly a mile and a half of depth since it was first recorded by the USGS changing the terrain. Because of the glacier's close proximity, icebergs can often be found floating in the bay. Due to a cold microclimate, timber is sparse in the Shoup Glacier valley, with the uplands consisting mostly of new growth forest of
