The snow wasn't the problem. There is more base now than on any closing weekend in quite a while, I was told. Going by snow alone, and preferences of the A-Basin folks too, another weekend at least would probably have been added. There was a lot of indecision right up until the end, apparently, until a cable problem was discovered.
I was in the parking lot this morning before 7 am, and an employee there said the A Bay brass had just informed them fifteen minutes earlier that definitely this weekend was it, the end.
They'd had another meeting this morning to re-evaluate the results of Poma lift technicians' inspections of the lifts this past few days (Wed and Thurs). Apparently the A-Bay lift techs earlier this past week had detected an "unraveling" problem with one of the main cables and had called in the experts at Poma, who came out right away: their conclusion was that the cable needs to be "splice" repaired quickly, so they advised closing for repairs. Unsafe.
That work will apparently be done during the next two weeks, during which time uphill climbing/skinning will probably be prohibited, I was told. Once the repairs are done, the employee I talked to thought uphill access might open back up.
