A group from the Calgary Outdoor Club scrambled Storelk and the walked the ridge to Mt. Tyrwhitt climbed down from there. As stated before route finding and bushwacking is needed to get up to Storelk. The ridge is not too difficult but pretty long, about 6.5 km.
Highwood Pass always gives you a nice head start (elevation) on a scramble. I had Directtissima on Yamnuska planned the next day and this short scramble (3000') fit the bill. Don't be looking for a trail to the summit though, not a well visited mountain. Definitely requires a little bushwhacking and route finding.
