Climbed yesterday, the day after cm20. We used the East Trail approach (all legal in theory), established by my trail partners and myself. This was the first summit by this route and adds 400' making for a true 10,000' gain.
We started at 11pm and reached the Chockstone by daybreak (7 hours). Scrambled and bouldered to reach the snow tongue at around 6,200. We used the West Direct couloir to summit at 3:30pm (our faster and younger member topped out at 2pm.). Cm 20 was gracious enough to posthole much of the powder down low which we took advantage of.
On previous camping outings we moved the approach line above Falls Creek up the hill 150 feet making for a low angle, sidehill traverse and bypassing the low bushy area. It's well marked.
