noticed this new small slide in between laps. 1 track going down skiers left side, might not have even noticed. saw another very similar small slide in same area, just 1000' west. Slide was very similar, same elevation, aspect, etc. but slightly larger 50' wide x 1' deep. running 100' vertically. Both crowns was just below exposed rocks/ guestimate 40 degrees.
