Shooting cracks and unstable pit on Alex Lowe

Skinned out to Alex Lowe peak today. Dug a pit on a northeast aspect below the east face of the peak. Got an ECTP 24 to break around 20 cm down. The slab was a knife hard sun/wind crust. Continued up avoiding areas where we noticed that bullet hard crust under the surface. On our decent we skied off the east ridge below the summit and on a skit cut got some shooting cracks, and a small wind slap to propagate but not slide. Skied the rest of the way down and didn’t notice anything else.
