We've encountered these structures in other areas and it is interesting to see the differences. We overheard a conversation between a naturalist and a visitor at Whitefish Dunes State Park earlier this winter and apparently one of the benefits of reduced deer populations is an increase in the spring wildflowers. No flowers apparent today, and at first, no cache was apparent, either. We looked like a bunch of fenced in deer, roaming about hoping to find something. I pointed out one spot that looked like the kind of place I'd put it, and when others began some excavation, it was in that spot. Whew! Lots of happy snowshoeing cachers in that fence after that! After finishing up at the park, we actually were treated to wonderful views of one of this friend's family members, a great end to a great day. SL TNLN TFTC
