AST 2 Pit - ST & PS column and EXT column test - WITH RESULTS!!!!

We dug a pit for our AST 2 on the edge of the ski boundary by Falling Star between Lost Boys and Mammoth Head Moose droppings - we did 3 column tests with the same result and 2 EXT's with the same result - We had the storm snow slab (ST) propogate and pop and the persistant slab (PS) drop down the January weak layer around 90cm deep. This is my first report for on a pit, so I appreciate any corrective criticism on how to better to this observation - I did not get a photo of the PS depth, but it was roughly 57cm from the ST - making a second report fot the PS
