Alma Park is a farming area closely associated with the Pleasant Hills township. While it is listed on some maps and documents as a town, it is nothing more than an area of settlement. The only obvious indication of Alma Parks's location is the old Lutheran Church that you would've seen when you decided to come looking for this geocache.
The geocache that you are looking for is in a small clear container remember to place it EXACTLY how you found it. Good luck!
