The Harmony Horseshoes (there are eight of them in total) are located off of Harmony ridge.
Many of the horseshoes involve navigating cornices, so make sure you are well versed in hazards of cornices before deciding to drop in.
You will be able to scope the horseshoe (line) of your choice from the Harmony Express, as the ridge will be located to your left when visible from the chairlift.
All the horseshoes are designated as double black diamonds, all being very similar in nature.
The middle chutes are the tightest, and they get steeper from left to right.
All horseshoes require you to "jump in" via the cornices on the ridge.
Any horseshoe you choose will lead you into Harmony bowl, and the groomer Harmony Ridge can be used to access the drop in as it traverses the ridge above.
