Intermittent clouds with minimal wind. Cold, 19-20 degrees. 18 inches fresh as we skied Brad's Line. Just on the NNE aspect of El Rollo noted a fracture line with no tracks into it. Measured at 36-37 degrees. Some tracks noted skiers left and may have been remotely triggered as reported elsewhere in obs. Appeared to have gone yesterday guessing natural. Skiing was sublime on low angle with multiple collapses on the skin track up and the biggest red flag...ski patrol bombs through out the whole day.
