The cache is a hinged container of transparent polyethelene with the approxomate dimensions of a thick trade paperback book, clearly marked with the cache name and geocaching.com URL. You'll be hard-pressed to fit anything much more than an inch thick within and still get the container closed.
Enough people have reported tripping and falling with varying degrees of hilarity and/or injury in the proximity of this cache during dry, warm weather that, combined with my experiences trying to check on this cache during snowy weather, I now have to advise against attempting this cache when there is ice or snow on the ground, unless you're a masochist, and you will almost certainly not find the cache if there is 10" or more of snow on the ground. Hint, hint. :)
Parking is easiest to the north/northeast/northwest, on streets; obey posted restrictions. Three fairly well-established trails lead within 100' or so of the cache site, though their routes are erratic and destinations often counter-intuitive. It's possible to approach the cache vicinity from all four cardinal directions on established trails, though some directions are much easier than others.
If you are approaching the cache from such a position that you are within 200' and have to negotiate a steep downward slope (what has come to be referred to as "the slide") and don't want to risk this rite of dubiously enjoyable passage (i.e. slipping and falling), you are most likely standing on, or have just passed across, a dirt path running generally north-south. Following this path to the north, while counter-intuitive, will bring you to a location on the other side of, and below, the cache, from which direction it is much easier to approach the cache vicinity.
Also, a note, if I may: When this cache was placed in 2004, there was a lot less undergrowth in these woods than there is today. This isn't a bad thing, but please keep in mind, as you squeeze single-file thru gaps in head-high shrubs and negotiate knee-high brush, that two years ago this area was more "parklike" and rather less "primeval forest". I wasn't trying to be a sadist. :)
On April 21st, 2007, a wildfire of unknown origin swept thru a fairly large section of forest in this area. While the cache was not affected, the area may be a bit unpleasant for the next few weeks, with a lot of ash blowing around and a quite persistent smoky smell.
Be warned that there is a history of sporadic paintball gaming to the west/southwest during summer weekends, though I have not observed any such activity since early 2005, and suspect this may no longer be a concern.
This area was part of the Willow Brook Fish Hatchery prior to WWI, then saw a number of small businesses in the '20s, '30s, and '40s to the east of the cache (how many foundations can YOU find? :) ) after the hatchery was relocated to the south. In the '40s or '50s this area east of Mounds Park was the Saint Paul Archery Range; if you search well you can still find signs of this short-lived recreational fad in the woods here and there...
The area is home to raccoons, fox, deer, owls, falcons, red-tail hawks, and at least one bald eagle, as well as the usual assortment of birds, squirrels, and so forth.
Despite the health of the woods, and the abundant wildlife, there's a goodly amount of soil contamination in the area, particularly in lower-lying spots near the marsh to the east. Those cacheing with four-legged friends would be wise to err on the side of caution and treat any water, even the natural springs, as suspect.
