The listed coordinated will take you to the Thompson Hill overlook,
which has a great view of the St. Louis River but is otherwise
unrelated to this cache.
You don't necessarily need a GPS here - I've provided an airphoto
with a big white arrow pointing right to the cache, with a couple
other photos to help you get your bearings. Just match the features
on the different photos, and you'll find yourself at the cache
site. It is also possible to derive the coordinates directly from
the photos, as shown below. This cache was inspired by Bennet's
"Big White Arrow" series, it's his fault!
First, get your bearings - this photo shows western Lake Superior,
the St. Louis river, larger lakes & major roads and the general
area:
Next, check out
scene 2 -this photo provides more detail on the cache area -
key features on the final image do appear on this photo. Heck, you
can almost see the cache...
And here is the
final image This one is a bit different, it's a color infrared
photo, vegetation shows up as red or orange, building and roads in
blue. But there is the cache, right at the tip of the arrow!
Some additional notes:
- While North is typically 'up', this is not necessarily
true for these photos.
- Cache is in a muggle-rich area - I have located it so that you
can be relatively innocuous in your search.
- Bring a pencil. A sharp one.
- There is wireless access at the cache site, and decent
coffee nearby. The owners are aware of the cache and might
give you a hint!
Geocaching guidelines state that GPS coordinates be available for
all physical caches, so if zooming between all these photos make
you dizzy, you can use these coordinates: N 46 44.xxx W 92 13.yyy,
where xxx is the geometric mean height of the photos (in pixels)+78
and yyy is the geometric mean width -110
Good luck & have fun!
