CT27 @~50cm, ECTN29 @~60cm. Both propagated on what I think is the week long thaw layer. Thin crust ~15cm down between last weeks snow & this weekends snow. This crust disappeared as we continued up in elevation. 140~150 cm total snow at the bottom of the slide and 220+ at the top. Dug a little bit at top of middle slide just to look at layers and compare, snow got progressively firmer with no apparent weak layers.
Weather was foggy, 29 °, light snow, no wind. Slight crust where snow got blown off around 3/4 of the way down the slides, but manageable.
