This is in a very sandy area which has its share of litter. Why is it that the litter is usually the same things? Is there a propensity? If you are going to mention the trash, as some have done, feel free to pick some up. 
It would be great to take a gunnysack along and fill it up.
The geocache called Mew http://www.geocaching.com/seek/cache_details.aspx?wp=GC1ZW4W is very close to the access point through the fence. The picture above shows a picture taken in the 30s and one taken recently. Click on it to see a larger view. If the lakes are NOT frozen you should park at 42 28.450 by 92 18.611 and walk around the lake clockwise to get to the cache. The other way is to park farther east then approach the cache from the east. It will be quite a hike either way! You can explore the beach or cut through the weeds. There are some narrow trails. I have replaced the time capsule with one that will not float away like the last one did when we had the record flood. The new one is located near an area where I have many fond memories. The sand and rock piles used to be right about where the cache is now. I remember the equipment used for dredging was near this spot. In fact some of the cables are still sticking out of the bank. Many of the agates and fossils I picked up from those rock piles as a kid are still with me. Once I found a perfectly preserved little shark's tooth made of brown colored chert as I recall. It was in the small rocks that pile up at the base of the big cones of sand. I can remember where on the pile I found some of the most memorable specimens, 40+ years ago. A guy called, "The Goat Man" used to live in this area. The story goes that he moved to a tree house nearby when his place was flooded. Back in the 60s I did find a big tree house in this area. It had a long rope that we used to swing down. Fishing is OK. Years ago the north and south lakes were joined during a flood that cut across what used to be Mitchell Avenue.
