The cache is a bit too large to be a micro. It is about 5 inches high and 3 inches in diameter with a 2 inch mouth.
The entrance to Mississippi River Community Park is along Cutters Grove Avenue at 45° 12.539' 93° 24.804'. In the winter, the driveway is gated shut but the walking paths are plowed.
The terrain conditions may vary widely over time. In warm weather, depending on the level of the Mississippi River, you may get wet feet getting onto the island. Although the cache should be safe from all but catastrophic floods, the cache may become entirely inaccessible during flood conditions. Please be careful.
