The cache is not located near a grave... If you find a fallen US flag, please stick it back in the ground at a veteran’s grave. As always, please be respectful and cache in, trash out. Also, please only search for cache during daylight hours.
You are looking for the gravesite of Air Force Airman 1st Class Donald Paul Groenke, a servicemember that served during the Korean War. Not many times that I cannot find any history on a veteran, but this is one of those times. Glad he made it through the Korean War as a young man.
Donald was born on what year, 19AB?
Then:
N 44 53.(450+AB)
W 93 58.(641-AB)
