These were washed ashore and most of them were empty. The last whorl was very large compared to the others. The drawing is natural size. These must be the most northern fresh water snails. The many loons seen on these lakes could well be feeding on these snails. +July. Sunday. Broken clouds with periodic sunshine.

From there we walked slowly upstream, sticking close to the dbanks along the river.
