Oppy Mountain is located on the border of Alberta and British Columbia, North of the head of Lyell Creek.

It was named in 1918 by interprovincial boundary surveyors after Oppy, a village in France.

In May 1917, many Canadian soldiers were killed in the area during the Third Battle of the Scarpe.

[6] Oppy Mountain is composed of sedimentary rock laid down from the Precambrian to Jurassic periods.

Weather conditions during summer months are optimum for climbing.
