Observed a natural persistent slab that ran this afternoon on a NE aspect BTL. 2 ft deep, small feature so only a D1.5 in size. Another group had crossed under the slope earlier in the day and had not seen it. From some steep easterly trees BTL, we remotely triggered two sympathetic persistent slabs. We were the 4th and 5th people on the skin track that day. One broke about 30 feet wide in relatively dense trees (D1.5) and the other broke about 300 feet wide (D2) about 400 feet from the trigger point. Both were a little less than 3 feet deep and failed on weak facets near the ground. There were also a handful of harmless sluffs and tiny storm slabs that ran overnight or today.
