Sun peaks slack country

Came across two separate glide cracks in separate terrain features in the sun peaks backcountry. Cracks essentially spanned the entire open slope in both cases- approx 150-200m across. Snow pack was relatively thin (1.1m) and the cracks were as wide as 4m in some places. Both slopes were predominately east facing 35 degree slopes at about 1900m with grassy alpine terrain underlying the snow pack.
