It would be possible using Map Compare. Put yourself in "Profile name" ("Compare with" can be empty). Add the "Cache type/size", "Difficulty/Terrain" and "Show Disabled/Archived" filters (the last being in case your find/s are no longer active) and set them appropriately and set "Show" to "one found".
Edit: This will give you the cache itself. You'll probably need to find your log to get the date.
