Observation: Hatcher Pass
Location: Wimp Bowl
Toured up to Wimp Bowl. We accessed the top of the bowl by gaining the ridge to the top of 4068. Encountered a rain crust just below fresh snow toward the top of the ridge (see attached photo) which we decided to boot pack. We descended a steep wind lip to the saddle/top of Wimp bowl to ski our first lap. Decided to ski a second lap but used the skin track going up the right side of the bowl.
Obvious signs of instability

During our two laps down and up the middle of Wimp Bowl we experienced whumphing. Slope angle was 20-21 degrees.

Also see additional Snow Pilot profile from James Howery "4068 E Aspect" to see variation in adjacent snow pit. This pit was dug approx 40 ft to the south on the same contour and varies from what was seen in this snowpack.
