Walked out from the dock to the area where the trail would be en route to the station. Farther out I got a flooded hole, the point of the paddle bit got through, but couldn't insert the hooked wire. Over 5 1/2 inches. Walking back towards shore I kept getting a measured 5 1/2 and one hole a little less. I'm thinking Sunday after 2 more cold nights would be a good time to do a run down the trail to check the ice thickness.
