The cache is not at the posted coordinates. You must first project a waypoint to obtain the true coordinates.
Use the posted coordinates to project the new coordinates using the following information.
880.542 Feet at a Bearing of 170.70475794846°
Don't know how to project a waypoint? There are several ways to do it, but here I will detail a simple easy way.
You can use the following link to help you out. Geocaching Toolbox Projection will take you to this screen.

Follow the instructions and input the info from above to get the coordinates. You can then copy & paste the new coordinates into your caching app or the website.
You can enter the new coordinates into Certitude to make sure you did everything correctly.
You can validate your puzzle solution with
certitude.
There are other ways to project a waypoint. I learned just by playing around in the geocaching app that I use to see how different things work.
Try playing around with your preferred geocaching app to learn how to use it to project waypoints. You might be surprised to learn something new about your app.
The cache is a small lock-n-lock container containing some small tradable items and the logbook.
As always, be sure to bring something to sign the log. Geocaching guidelines state for physical caches other than challenge caches, any additional logging requirement beyond finding the cache and signing the log must be optional. Caches can be logged online as "Found" after the geocacher has visited the coordinates and signed the log. Your log will be deleted if you did not sign the log.
Congratulations to GenieCache for being FTF! 🎉🎊🥳
