Comments
blue bird I observed an avi in Toll Bowl #3 in Toll Cyn today. Note: Toll Cyn drains into East Cyn. Avi probably occurred 2/21/10. Human triggered, intentional???? Slope is around 30o, aspect NNE and approx 7,600 ft. in elevation. Size is 6"-24" (some wind loading because it sits below a saddle) X 120' X 60'. Avi has a thunderbolt configuration, thus the 120' width . Weak layer is apparent surface hoar. Note: I've been skiing in Toll cyn for 12 yrs with over 800+ days and I've seen this bowl slide only 1 or 2 times in those 12 yrs. k
