Surface slab(s) popped out whilst skinning up to Lake Peak ridge on N aspect at 10,300. Was on the slab(s) when it went but angled right at 45 degrees upon impromu skin descent into shallow rock band on immdiate right (east). Stopped immediately. No consequences. Notably, had felt as though there would be small micro-wind-slab pop due to increasing angle and slight slope buldge and wind loaded snow appearance and close proximity to rideg line. Even with awareness of these factors, made decision to move across and ascend to ridge due to general stubornness, desire to attain pre-meditated goal, and probably most importantly, the general benign nature terrain below combined with confidence in my decision that what would pop, if anything. would be very small. Got a bit more than bargained for. Again, quickly off slab and no ride or resultant consequence. Skied down bed surface a bit and with my pal, Ferg, inspected the make up of this event. Conclusions drawn on hill and now upon a half day's worth of reflection: the Thursday/Friday storm snow settled (heat and wind) and then the wind blew and it loaded. Bingo.

Take aways: 1) Humbling. 2) Familiarity with slope/location/terrain, while nice in theory and conversation, invites error. 3) Minimizing the signs you see, say for the sake of getting somewhere (i.e. summit for a view) with a pal on a familiar slope, invites further error. 4) Overselling in one's mind the deep stabilty of spring, you guessed it, invites error.
