The cache is not at the posted coordinates.
You discover a weathered journal tucked behind a red rock. Its pages whisper clues about the treasure you seek:
A. Begin your journey where the earth arches high. Find the name of Utah’s most famous natural arch. Count the letters in its first word only. This is your first number.
B. Next, find the number of U.S. national parks located within Utah’s borders. Multiply this by the number of colors in the Utah state flag to reveal your second number.
C. Finally, visit Arches National Park—at least in your imagination. Landscape Arch has a light opening 306 feet across. Use the number of feet as your third number.
Let Utah’s arches, colors, and landscapes guide you to the hidden cache!
AB is A followed by B. No math. Just concatenate.
The final coordinates would be N 40 45.[AB + 150] W 112 31.[C - 43]
