Watson Lake is located in the Boreal Forest region of the Liard Basin, amid marketable timber stands (needle leaf with some western deciduous species). The Simpson Range of the Pelly Mountains lies just to the north. Soils are well-stratified and gravel except in the southwest part near the Alaska Highway where impermeable clays and silts occur close to the ground surface. There is also bedrock near the surface in developed areas and gravely moraine deposits.
A specific geologic formation in the Watson Lake area is the Liard plateau, a board plateau of even top ranges of hills created by intensive folding of the sedimentary strata from the Paleozoic Age. Part of the Slewyn Gold belt, the Plateau is transversed by the Tintina Trench, a mineral rich fault line slashed below the plateau. The greater part of the Trench valley in the Watson Lake region contains the Liard River.
Because of its location and physiographic features, Watson Lake is subject to great variation in climate from year to year. Although Watson Lake is located in the southeastern Yukon, Prolonged cold spells can occur in the winter, primarily because the town is far inland from the moderating influence of the Pacific Ocean and lies in the shelter in the Liard Basin. No permafrost exists in the community or in the immediate vicinity. However, there are some scattered permafrost pockets in certain isolated areas. Frost penetration in the woodlands is approximately one meter and in clear areas it is three and half meters. In general the climate of Watson Lake is characterized by long, cold winters with dark nights, and by mild summers with long sunny days which helps to offset the limited growing season. The coldest month is January and the warmest weather is usually in July. The driest is April and the wettest month is September. Also December is the month with the greatest average snowfall.
