The coordinates above take you to the sharpest-angled corner or
intersection in Dubuque. Here, two streets (in this case, two parts
of the same street) intersect at the smallest angle of any place I
could find in town. GPS waypoints along the middle of the streets
estimated the angle measurement here as 6.3°. Compass measurements
along the curbs gave 4-6°. The only other corners that came close
were the upper bend of the same street (~10°), and 12th and Grove
Ter. (15°).
There is a $20 gift certificate to any Olive Garden or Red
Lobster in the cache for first finders. Otherwise, typical cache
contents. Good luck!
The clue to the final location is located 11200 feet from the
sharpest corner in the direction of the street that makes a larger
angle with due north.
The former final location is located N+90 feet from the sharpest
corner in the direction of the street that makes a smaller angle
with due north. N is the product of the following three
numbers:
-The number of letters in the clerk’s first name
-The last 2 digits of the year that many people labored
courageously to protect Dubuque
-The last 2 digits of the year Col. Richard ended his term
NOTE: The short distance that both streets extend straight ahead
from their intersection before bending or turning makes it hard to
get an accurate angle measurement on either one. Due to this,
ASSUME the following. The angles aren’t exactly right, but
they make the math work out right.
(11Mar06) Due to repeated thievery, the physical cache has been
moved to a new location in the general area of the old location. In
order to get the new final coordinates from the old final
coordinates, assuming the old final coordinates are XXºXX.ABC' N,
YYºYG.DEF' W, replace B with B-6, D with D-6, E with E-4, and G
with G+1. A, C, and F remain the same.
• The upper section of the street intersecting here forms a
47.55° angle with due east.
• The lower section of the street intersecting here forms a
37.22° angle with due east.
This information makes it unnecessary to visit the sharpest-angled
corner coordinates, but it is nonetheless an interesting spot to
see.
If you’re interested, the sharpest-angled corner was
determined using topo maps, waypoints, and compass readings using
the following criteria:
• Both streets must run straight for a significant distance
up to the corner.
• Both an intersection and a bend in the same street can
qualify.
• Zero degree corners do not qualify. This eliminates parallel
streets separated by a wall like Cornell and Montrose Ter., and
11th and Grove Ter.
• Exit ramps and turn lanes, etc. do not qualify as
streets.
Please replace cache as you found it. It is a relatively visible
location.
