Welcome to the Yukon Geological Survey's Integrated Data System (YGSIDS). We are in the process of merging all of our data into one system (see the current state of the conversion process). When this process is complete, the YGSIDS will include all of the Yukon Geological Survey's publicly accessible data.

Map Location


This map illustrates the geography of Beringia, the land bridge that formed between North America and Asia during the last glaciation. Humans crossed Beringia from Asia to North America during the glacial period depicted on this map. Lakes and drainages have been reconstructed to provide a better perspective on the environment of the land mass according to bathymetric data having a grid spacing of 1 km (100 m for Norton Sound). Some of the lake basins are shallow and may have been wetlands rather than open water bodies.
