Comments: 

Noticed these 2 slides around 9:30am 1/13/18. Went back at the end of the day to check it out up close. You can see the track cutting across the top of the slope. They were able to escape the slab and avoid being carried. There was no evidence of them dropping onto the bed surface. They must have been able to maintain their speed before the farthest lookers left portion of the crown broke away. Crown averaged 35 degrees and 2-2.5 ft deep 100 ft wide.
