Explosive work on Ipanna face
quick note of about 30cm of graupel above lower density snow earlier in the storm.

- <p>Perhaps a combination of storm snow and wind drifted snow. Many widely propagating soft slab avalanches (from yesterday) noted on easterly facing Bob's Knob (<a href="https://utahavalanchecenter.org/avalanche/44529">as reported this morning</a>). These roughly similar band as noted in Butler Fork by Craig Gordon and others. Too much exposure to investigate crown - but based upon snow pits - imagine wind loaded 'graupel slabs' overlying lower density snow from Wednesday night. These avalanches perhaps 1-2' deep (up to 3' where wind loaded) and 700'+ wide, cleaning out the standard Bob's slidepaths by taking out immature aspens. (pics below). Other potential layering included what looked to be recrystallized graupel 60cm down though ECTX (elicited via pry-bar).</p> <p> </p> <p>Control work with avalauncher this morning produced a good size 3+ avalanche 1-2' deep and 1000' wide on Ipanna face at 8400' east facing. This is outside of Sundance but threatens the resort from above. Pics below; likely similar layering as above. </p> <p> </p> <p>Lost Creek natural from mid-morning as reported </p> <p> Expect these to gradually stabilize depending on increased stress from this next storm. </p> <p> Other concerns: health plumes of wind drifted snow noted along exposed ridgelines. Graupel pooling beneath cliffbands or at steep/less steep transitions should be anticipated. </p> <p>Plenty of wet loose sluffs noted below 7500' from rain/snow line. This should rapidly heal with tonight's cold front unless insulated by a larger amount of storm snow. </p>
Fast and surfy graupel skiing above 7500'; damp below (as per rain/snow line from yesterday). 23"/3.28" SWE since Wednesday.
