Hudson Bay Mountain 'ozone'

Fitness skin last afternoon from town up to 1700m above the ozone. Observed strong gradients in temp effects on snow pack with overall less heat penetration than I was expecting. These are VERY limited observations and did not include strong solar aspects and steeper slopes, or higher alpine observations. At lower alpine ~1700m on gentle northeast aspect in shallow snowpack (~50cmHS) only the very upper 5cm was moist. Below that to ground were dry and loose facets and well preserved depth hoar. Ski pen 3cm, foot pen variable ~20cm. Air temp ~+10 at 3:45 pm. At lower edge of parkland/treeline ~1500m the moist snow was about 15cm deep with skin pen 3cm. By below treeline 1400m the snow was isothermal on shallow steep east aspect cliffed terrain where one could cut and release snow to ground with wet facets easily running over rock and heather. Ski pen variable supportive (~5cm) to punching deep into isothermal facets (~40cm). I did not test deeper locations and in those cases I am uncertain if the whole snowpack is isothermal. I have been hoping that this heat would nuke the snowpack and accelerate a transition to corn/spring snow later in April. I'm now thinking that perhaps only steep solar aspects have any real penetration and other aspects will have had sufficient radiation cooling even with night temps above 0 and to create a mixed bag of varying crust thicknesses and density with lots of facets and depth hoar remaining. More obs would be nice to test this thesis.
