A great looking alpine peak still with new potential. As the story goes, this was Brian Greenwood’s first Rockies FA done in 1956 rated low 5th class.
In Aug.1977, G.Spohr and J.Martin climbed the east face from the large bowl rated 4th class with much route finding.
In the summer of 1976, E.Grassman lead a way up the north ridge and is recorded as 5.5 in steep sections.
In December of 2002, D.Marra and J.Condon climbed the same face as the Greenwood party: ‘Fun Fun’ 1000m V, WI4+R 5.9 – hike bowl to 50m of WI2+/3, go up steep bowl to 60M of WI4+R followed by 180m of easy ice/rock to more snow sloggin’, then 60m of 5.9 WI4, snow, 60m of 5.6, 20m of WI4 5.8 , then a 5m 5.9 roof with touch more mixed terrain to the ridge. From near ‘A’ in the photo, they descended SE down a bowl out to the Smith-Dorrien road.
For access: as of 2005, park at Fortress Junction, bike the road if it is closed(?) to below the desired route. Routes #C-E can be had by hiking up an enormous avalanche runout that nearly touches the ski road; you may be able to park along the road. Please note these lines on the photo are approximate.
In November 2006, Tony Devonshire and partner were up climbing the ice route Fun Fun, when while seconding the first WI3 ice pitch the huge snow bowl above released naturally and swept Tony away to the lower snowslope where he died of suffocation from being buried.
In autumn of 2010 a plaque for Tony was placed on a rock far to the east of Mt.Inflexible at a spot that overlooks this pretty mountain and it’s history of triumph and tragedy.
