This is #22 of the Oyate Trail Geocache series. Starting just north of Sioux City, the Oyate Trail follows Highways 50 and 18 along the southern border of South Dakota all the way to Edgemont. There are 110 geocaches spaced approximately every 3 miles along the trail. These caches are numbered from east to west, #1 to #110.
The first 50 geocachers to find and log at least 100 of the 110 caches along the trail are eligible for an Official Oyate Trail Geocaching Coin. To apply for your coin, email Charlie @ saltcamp@gwtc.net with all 100 + codes that you will find in the upper right corner of the cache log. These codes must be in order, #1 to #110 for example: 1D, 2O, 3N, 4T, etc. Include your name and address so if the codes are correct, Charlie can send you your coin.
This cache features a scenic view of a wide, flat expanse of South Dakota plains to the North and Northeast. This area was once covered by a great Inland Sea.
The changing of global sea levels over millions of years was a major factor in determining the ancient geography of southern South Dakota. Through much of geologic time, salty warm water seas covered the interior great plains of the United States.
During the late Cretaceous Period, 65 to 80 million years ago, rising ocean levels several times produced flooding that created inland seaways. These seaways extended from the Gulf of Mexico to the Arctic Circle and divided North America into two parts.
Glacial action over the northern plains, about 12,000 to 15,000 years ago, was instrumental in forming the rolling topography of the Missouri River breaks areas to the south.
No need to enter private property or cross fences to access this cache. Enjoy!
