Quick report
Shastina via Hidden Valley and Cascade Gulch from Bunny Flat. Traveled climber's left of creek which provided good footing until ~10,500 feet when very loose scree on south face of Shastina made travel up remaining snow line in creek essential. Snow was very slick in early morning but edge of snow/rock provided suitable traction without crampons.
