Jarvis Cemetery isn't really big, but it does have a lot of people buried there. Possibly former students, the cemetery has a few graves that date back to the early 40s or 50s. Anyway, you are looking for a small peanut jar, but I must warn you, the coords may be a little off, for it was cloudy when I placed this cache.
