Lake O'Hara Map by GemTrek

On the front is a 1:20,000-scale topographic map covering the entire Lake O'Hara trail network with all of the hiking trails and alpine routes labelled. The contour interval on the map is 25 metres (80 feet).

On the back of the map are descriptions of all the trails shown on the map - Lake O'Hara Lakeshore, Lake Oesa, Lake McArthur, Opabin Plateau, and Linda Lake to Cathedral Prospect. Also described is the entire alpine route - Wiwaxy Gap/Huber Ledges, Yukness Ledges, All Souls' and Odaray Grandview Prospect.

As well as noting highlights, the trail descriptions also include distance, elevation gain and directions to the trailhead. The trail descriptions were written by Bruce Millar of Lake O'Hara Trails Club and Lake O'Hara Lodge. Several photos accompany the text.
