Doing a trip up Old Army Pass into Miter Basin next week with a planned camp at Iridescent Lake. We would like to summit Le Conte from Iridescent. The only information I can find is the brief description of the West Couloir in Secor. Any additional information on this route would be greatly appreciated.

Also is it possible to go from the south slope of Langley to Iridescent directly and not down to Soldier Lakes and into the bottom of the basin.
