Mountain goat (Oreamnos americanus) annual aerial helicopter survey data for the area of Lake Louise, Banff between 2002 and 2017.

The aerial survey transect runs from just northwest of Lake Louise, near Ross Lake, to just south east of Taylor Lake. These surveys have been conducted annually since 2006, with two additional surveys conducted in 2002 and 2003. The transect elevation is set at approximately 7500 ft (2286m) and all observed goats are counted.
