Geotechnical data comes from investigations performed by geotechnical engineers to obtain information on the physical properties of soil and rock underlying a site for proposed structures. The investigations include surface exploration and subsurface exploration of a site. In addition, site investigations will often include subsurface sampling and laboratory testing of the soil samples retrieved. The digging of test pits and trenching may also be used to learn about soil conditions at depth. Geotechnical data is relevant to our permafrost database as it contains logs of ice encountered at various depths. Yukon Geological Survey has been compiling geotechnical data from various organizations and branches. The main datasets being compiled are the following: Northern Climate Exchange Community Services, Land Branch Energy Mines and Resources, Abandoned Mines Transportation Engineering Branch Alaska Highway Borehole Database Agriculture soil profiles Distributed from GeoYukon by the Government of Yukon .
