Notes

From email 1/26/24: "7 ANFO jug shots were used in D-Rt and S-1. [Areas not open to public skiing yet this season]

Joel's Belly which broke 12-18" deep 50+' wide on the wind loaded south shoulder above the joel's zip drive - majority of the debris didn't go too far, southside portion rolled off the stubborn angle and down onto the z-fan.

Z-Chute southside above traverse to lost shot bowl removed the seasons snowpack down to the basal crust. 50-100 ft wide, pulling the faceted snow off the steep rocky wall to the south and put a lot of debris on the Z-Fan and ran 100ft below the south bowl traverse.

Middle of Lost Shot bowl released but not very big."
