LOCATION: Hickory Run State Park, Carbon County, PA
Finding this letterbox involves running the advanced permanent (trim)
orienteering course at Hickory Run State Park. See the notes below.
One way to to get to the park is: From exit 35 of the PA Turnpike (I-476),
turn right directly after passing through the tolls (onto PA-940 west).
After about 2 miles, turn left onto PA-534 east. From there, it is
about 5.5 miles to the park office where you will have to ask a ranger
for the Hickory Run Permanent Orienteering Course Map.
Review the entire pamphlet. When ready, navigate to the start triangle
of the advanced course. It is marked by a very faded trim orienteering
control marker (similar looking to the illustration in the pamphlet).
You can confirm you are at the right place as there is the start of a
concrete dam 41 paces from the marker, on a bearing of 204 degrees.
Run the course and record the two letter code at each control. When you
get to control #20, you can begin to hunt for the box. The control
codes noted are a key into a formula to determine the number of paces
and bearing from control #20 to the hiding place, which is under a rock
(the box is concealed by a second rock as well, and can be retrieved
by moving the second rock, and sliding it out).
Here's how it works: the first letter in each two letter control code
is used in the pace formula, and the second letter in each two letter
control code is used in the bearing formula (e.g., when calculating
the pace count, totally ignore the second letter in the control code).
Count the number of times each letter occurred as the first
letter (pace), and as the second letter (bearing), and plug into the
formulae below (remembering to wrap the bearing calculation at 360, if
pace = 29*A + 10*B + 5*C + 83*D + 13*E + 3*G + 25*H + 8*O + 19*M + 57*S + 12*T
bearing = 201*A + 8*B + 81*C + 5*D + 52*E + 27*G + 72*H + 3*O + 61*M + 45*S +
36*T + 13*V
Example: If the control codes were AA, AB, AC, and BA, the box would be 97
paces (29*3 + 10) at bearing 131 (201 + 8 + 81 + 201 = 491 (- 360)) from
