The North East aspect of Mount Lineham
|[ Sizes: Orig | Large | Med | Small | Thumb ]|
The North East aspect of Mount Lineham as seen from the Akamina Parkway. Waterton Lakes National Park, Alberta, Canada.
When viewed from the Akamina Parkway a horizontal black stripe is very noticeable on the impressive North East face. This stripe is the Purcell Sill, created when molten rock was injected under incredible pressure between layers of sedimentary rock. The magma (molten rock) then slowly cooled to become diabase, the coarse grained equivalent of basalt. Igneous rock such as this is very rare in the Canadian Rockies.
