The line is accessed via Secret Bowl from the top of 7th Heaven Express or Horstman T-Bar. To find Purple Haze, head towards the right hand side of cougar chutes, hugging the rocks and small trees on the right. Once it's just trees creep/traverse through them and you'll find yourself on the edge of some more rocks. Proceed with caution here as certain parts build a cornice depending on the snow/conditions of the year. Scope out your entry from this point then drop in and enjoy!

Make sure you're either going with someone who knows this route well, or if exploring alone go when there is good visibility. Clouds often sits around this area and the light is often flat, making your crucial depth perception a challenge!
