The cache IS located at the posted coordinates.
This is a challenge cache. You must meet the requirements in order to log a find. You may sign a the physical log at any time, but you may only log the find online after the log is signed and the challenge task has been met. You can log a “write note” if found prior to meeting the requirements.
Do you love to travel? If so, this is a challenge for you. To qualify for this challenge, you must find a cache in 10 countries. This challenge uses the countries list used on your statistics page, meaning some territiories that are part of another country are counted as their own country (e.g. Sint Maarten, British Virgin Islands, etc.) - this makes it even easier to fulfill this challenge!
The United States counts of course, so you're likely at least 10% done with this challenge already!
The difficulty rating of 5 is based on the challenge; the terrain rating is based on the hide.

The cache is a magnetic hide-a-key in a typical spot. There is no need to go into the blackberries or down any slopes.
