Montney Formation

The Montney Formation is a geological layer in British Columbia that extends across vast areas and consists of fine-grained siltstone. This sedimentary rock layer holds substantial natural gas reserves trapped within its porous structure.

The formation developed during the Triassic period, hundreds of millions of years ago, in shallow plains and delta regions. The accumulation of mud and sediments over extended periods created the layered structure we see today.

Local Indigenous communities maintain strong connections to the lands where the Montney Formation lies, participating in discussions about resource management and preservation.

The formation lies beneath the surface and is not directly visible, so understanding it requires geological maps or information centers. Visitors can explore museums and exhibitions that explain the regional gas deposits and geological history.

The Montney Formation extends into Alberta as well and ranks among the largest natural gas sources in North America. This subsurface resource deposit shapes the economy and development of multiple provinces in the region.
