Probably the hot dry weather we're enjoying in BC. Did you seal the ends and back(if you de-barked it). Being from a dry place you are going to have to slow down the drying. Out of the sun, out of the wind, I'm trying wrapping it in paper. I heard that slows it down some. My experience is with Ocean Spray mostly but I have done a couple of pieces of Saskatoon. No problem here on the coast buy you have major dry up there.
