There is nothing hidden at the posted coordinates. You must solve the puzzle below to obtain the actual cache coordinates. You will be seeking a matchstick container. Please use appropriate stealth when searching, and be sure the cache is concealed as well as (or better than) you found it.
It was almost exactly 10 years ago that teamajk started caching, and this occasion, like all such anniversaries, has led "J" to look back over the years, reminisce about fun times and good friends, and wonder at the swift passage of time. This cache is the thirteenth in what we hope will be an informal series of caches throughout the rest of 2020, with puzzles which may bring to mind some of our previous work while incorporating some new twists. Be sure to save the bonus information from the geochecker for the series finale.
Now that we're well into December, I'm finding myself in a "race against time" to see if this series will actually finish while it's still 2020. Looking back over the years, I've had a lot of fun creating puzzles around a winter or Christmas theme. GC4V4MJ, GC38XJ0, GC411Z9 are a few that come to mind. So before 2020 is in the books, I'm presenting you with this little puzzle. You'll be seeking a keyword/phrase to enter into certitude. Here's my list. Can you check it, twice?
