This is a puzzle geocache. There is no container or relevant information at the posted coordinates.
The United States has 60 National Parks. All of these parks have different beauty between each other. The oldest is Yellowstone (1872), and the newest is Gateway Arch (2018). Each National Park has a 4 digit “Alpha Code.” The Alpha codes are made up of the first four letters of the park name. But if the park has more than one word, it takes the first two letters of the first two words. But there are some exceptions.
Examples:
1 word: Yosemite - yose
2 word: Petrified Forest - pefo
2+ word: Black Canyon of the Gunnison - blca
Exception: Carlsbad Caverns - cave
I will hide a geocache to honor all of these parks. I will do 6 groups of 10 caches. Each of these are a puzzle with 6 questions.
I used Wikipedia for this information, as it gives it all on one page. Also say in your log if you have been to this park. If you have, please post pictures.
This cache was given away at GC6FR4G, FTF on Feb 29? No, on Feb 38th (3/10). The winner got at least a 7 day head start on the Pre-FTF. The final cache has 2 spots for FTFs, a Pre-FTF, and a Post-FTF.
The final container is at: N 37° 59.ABC W 122° 07.DEF
A. The park is A,093,077 acres on the Alaskan Peninsula
B. The crater lake in the inside of Mt. Katmai has an estimated surface elevation of B,220 feet above sea level (use Mt. Katmai page)
