Middle Spines Arrowhead Bowl Map

This is a popular ski touring route which is generally considered to be severe. It's very remote, it features medium exposure (e2) and is typically done between December and June. From a low point of 2.7 km to the maximum altitude of 2.8 km, the route covers 220 m, 0 vertical metres of ascent and 141 vertical metres of descent. It's graded 3.3 and Labande grade 5. You'll need skins to complete it safely.


These Flutes and Spines are steep and short, but great for spinning laps. They are a great spot for technical training due to the low exposure below. Spot your landmarks from below, then convince yourself to go for it once on top.



Steep skiing at 38-45 degrees. This requires very good technique and the risk of falling has serious consequences.
