White Horse Bluff is a subaqueous volcano[1] in Wells Gray Provincial Park, east-central British Columbia, Canada.

Subsequent erosion by glaciers and meltwater has exposed these dykes which give the impression that a giant hand has plastered gobs of lava onto the face.

Unlike most formations of columnar basalt which are vertical like organ pipes, these are horizontal and the ends of the columns point out, rather like the tiles on a shower wall.

[2] Mac and Cecile McDiarmid built one of their Clearwater River fishing camps at the foot of the White Horse Bluff in the late 1940s.

Eventually, the McDiarmids operated four cabins or fishing camps along the river and their home base on the Clearwater Valley Road was called Trophies Lodge.
